  • Infrared Thermography Versus Conventional Image Techniques in Pediatrics: Cases Study
    VipIMAGE 2017, 2017
    Co-Authors: Olga Benavent Casanova, Jose Ignacio Priego Quesada, Rosa Maria Cibrian Ortiz De Anda, Francisco Núñez Gómez, Rolando González-peña, Teresa Cuenca Bandín, Rosario Salvador Palmer
    Abstract:

    The use of Infrared Thermography has been shown to be useful in several areas. Its applicability in medicine is based on the fact that the skin emits spontaneously and continuously Infrared radiation, whose body distribution is symmetrical in a healthy individual. Infrared Thermography can offer an alternative to X-rays for a large number of diseases related to peripheral vascularization. In these cases, Infrared Thermography can avoid the use of biologically ionizing radiation. This is of special interest in pediatric patients who, because of their age, are more radiosensitive.

  • Application of Infrared Thermography in Sports Science - Application of Infrared Thermography in Sports Science
    Biological and Medical Physics Biomedical Engineering, 2017
    Co-Authors: Jose Ignacio Priego Quesada
    Abstract:

    This book addresses the application of Infrared Thermography in sports, examining the main benefits of this non-invasive, non-radiating and low-cost technique. Aspects covered include the detection of injuries in sports medicine, the assessment of sports performance due to the existing link between physical fitness and thermoregulation and the analysis of heat transfer for sports garments and sports equipment. Although Infrared Thermography is broadly considered to be a fast and easy-to-use tool, the ability to deliver accurate and repeatable measurements is an important consideration. Furthermore, it is important to be familiar with the latest sports studies published on this technique to understand its potential and limitations. Accordingly, this book establishes a vital link between laboratory tests and the sports field.

  • Infrared Thermography in the architectural field.
    The Scientific World Journal, 2013
    Co-Authors: Carosena Meola
    Abstract:

    Infrared Thermography is becoming ever more popular in civil engineering/architecture mainly due to its noncontact character which includes two great advantages. On one side, it prevents the object, under inspection, from any alteration and this is worthwhile especially in the presence of precious works of art. On the other side, the personnel operate in a remote manner far away from any hazard and this complies well with safety at work regulations. What is more, it offers the possibility to quickly inspect large surfaces such as the entire facade of a building. This paper would be an overview of the use of Infrared Thermography in the architectural and civil engineering field. First, some basic testing procedures are described, and then some key examples are presented owing to both laboratory tests and applications in situ spanning from civil habitations to works of art and archaeological sites.

  • Infrared Thermography to detect residual ceramic in gas turbine blades
    Applied Physics A, 2008
    Co-Authors: Carosena Meola, Giovanni Maria Carlomagno, M. Di Foggia, O. Natale
    Abstract:

    A serious problem in the production of gas turbine blades is the detection of residual ceramic cores inside the cooling passages; in fact, the presence of even small ceramic pieces affects turbine performance and may cause difficulties in successive manufacturing. Therefore, it is important to have a non-destructive technique that must be capable of detecting tiny ceramic fragments in a fast and easy way. In this perspective, the suitability of Infrared Thermography was investigated within cooperation between the University of Naples and the Europea Microfusioni Aerospaziali S.p.A. (EMA). Several blades of three different types were inspected revealing that in many cases Infrared Thermography can discover small ceramic fragments which were missed by X-ray inspection. In addition, Infrared Thermography allows gaining of information about other types of anomalies (e.g., surface defects) during the same testing step (by eventually changing the test parameters) and then saving time and money. The obtained results look promising in view of introducing Infrared Thermography among industrial instrumentation as an alternative to, or integrated with, the most currently utilized non-destructive techniques.

  • Analysis of composites with Infrared Thermography
    Macromolecular Symposia, 2005
    Co-Authors: Carosena Meola, Giovanni Maria Carlomagno, Antonino Squillace, Umberto Prisco, Renata Erica Morace
    Abstract:

    The aim of this study was a non-destructive evaluation of composites through their behaviour under thermal stimulation. Such behaviour was monitored by Infrared Thermography. Several specimens were fabricated involving: glass/epoxy with inclusion of foreign materials; carbon/epoxy with backdrilled holes; carbon/epoxy with impact damage; Glare® failed in bearing way. The obtained results prove that Infrared Thermography is capable of detecting the materials inhomogeneities and/or damage listed above. In particular, lock-in Thermography is capable of supplying useful information about: the distribution of the adhesive thickness in composite structures; the distribution of the paint thickness; the behaviour under load of aluminium layers and glass fibres in Glare®.

  • The use of Infrared Thermography for materials characterization
    Journal of Materials Processing Technology, 2004
    Co-Authors: Carosena Meola, Giovanni Maria Carlomagno, Luca Giorleo
    Abstract:

    Abstract The aim of the present experimental study is to highlight the help provided by Infrared Thermography in the characterization of materials. Infrared Thermography is a two-dimensional, non-contact technique of surface temperature mapping which can be usefully exploited for quality assurance of manufacturing processes as well as for non-destructive evaluation of end products. Non-destructive evaluation with Infrared Thermography can be performed in two basic ways: pulse Thermography (PT), or modulated lockin Thermography (MT). Both techniques are able to reveal material inhomogeneties, which can arise either during manufacturing processes, or in service. In particular, within the MT technique a phase angle value may be associated to a specific characteristic (density, porosity, hardness, etc.) of the material. Thus, MT can be exploited for characterization of many materials either metallic, or plastics, composites, etc. which are commonly used in different fields: alimentary, architectural, automotive, aeronautical, mains. Results prove the capability of MT to discriminate between materials very similar and this feature can be advantageously exploited to evaluate modifications that occur in material characteristics as consequence of ageing, or exposure to adverse environmental conditions.

  • Recent advances in the use of Infrared Thermography
    Measurement Science and Technology, 2004
    Co-Authors: Carosena Meola, Giovanni Maria Carlomagno
    Abstract:

    Infrared Thermography transforms the thermal energy, emitted by objects in the Infrared band of the electromagnetic spectrum, into a visible image. This feature represents a great potentiality to be exploited in many fields, but this technique is still not adequately enclosed in industrial instrumentation because of a lack of adequate knowledge; at first sight, it seems too expensive and difficult to use. The aim of the present paper is to shortly overview existing work and to describe the most relevant experiences devoted to the use of Infrared Thermography in three main fields, i.e. thermo-fluid dynamics, technology and cultural heritage, which have been performed in the department the authors belong to. Results may be regarded from two points of view, either as validating Infrared Thermography as a full measurement instrument, or as presenting Infrared Thermography as a novel technique able to deal with several requirements, which are difficult to perform with other techniques. This study is also an attempt to give indications for a synergic use of the different thermographic methods and sharing experiences in the different fields.

  • Unsteady Boundary Layer Transition Detection with Local Infrared Thermography (Vollbeitrag)
    'Springer Science and Business Media LLC', 2020
    Co-Authors: Mertens Christoph, Wolf Christian, Gardner Anthony
    Abstract:

    A new approach to measuring unsteady boundary layer transition in periodic processes with Infrared Thermography is introduced. The radiation from the heated suction surface of a pitching airfoil model is measured with an Infrared camera. The extraction of the extrema of the measured radiation signal at fixed model locations yields instants of the motion phase that correlate with the occurrence of boundary layer transition. The analysis of the extrema of the signal's gradient produces results that are equivalent to the results acquired by optimized differential Infrared Thermography, and it provides insight into the origins of the systematic error of that technique. It is demonstrated that the local Infrared Thermography approach can be readily extended to measuring two-dimensional boundary layer transition fronts

  • Unsteady Boundary Layer Transition Detection with Local Infrared Thermography
    Notes on Numerical Fluid Mechanics and Multidisciplinary Design, 2019
    Co-Authors: Christoph Mertens, C. Christian Wolf, Anthony Donald Gardner
    Abstract:

    A new approach to measuring unsteady boundary layer transition in periodic processes with Infrared Thermography is introduced. The radiation from the heated suction surface of a pitching airfoil model is measured with an Infrared camera. The extraction of the extrema of the measured radiation signal at fixed model locations yields instants of the motion phase that correlate with the occurrence of boundary layer transition. The analysis of the extrema of the signal’s gradient produces results that are equivalent to the results acquired by optimized differential Infrared Thermography, and it provides insight into the origins of the systematic error of that technique. It is demonstrated that the local Infrared Thermography approach can be readily extended to measuring two-dimensional boundary layer transition fronts.
