Materials Selection of steam-phase change material (PCM) heat exchanger for thermal energy storage systems in direct steam generation facilities
Solar Energy Materials and Solar Cells, 2017Co-Authors: F. Javier Ruiz-cabañas, Aleix Jové, Virginia Madina, Cristina Prieto, A. Inés Fernández, Luisa F. CabezaAbstract:Phase change Materials (PCM) is one of the most interesting solutions to be used in thermal energy storage (TES) systems for direct steam generation (DSG) thermosolar facilities. Properties such as high energy density and energy storing/delivery at constant temperature bring PCM based systems in excellent candidates for DSG facility storage units. Accordingly, LiOH-KOH peritectic mixture, with a melting point of 315 °C and an enthalpy change of 535 kJ/kg, has been reported as attractive solution for the saturated storage module in DSG plants. A steam-PCM heat exchanger is the critical component to carry out the thermal transference between both substances. Although Materials Selection to be applied for steam applications is well known, lack of knowledge is detected in the field of high temperature hydroxides corrosion. Therefore, three metallic Materials, A516 Gr70 carbon steel, A316L stainless steel and Inconel 625 Ni-base alloy, have been evaluated to determine their corrosion performance after hydroxides exposure. While A516 Gr70 was discarded for this application due to high corrosion rates, A316L and Inconel 625 displayed good corrosion resistance after 2640 h. Finally, A316L stainless steel was selected as potential candidate for the construction of the steam-PCM heat exchanger considering cost and thermal efficiency optimization.

A state-of-the-art survey on the influence of normalization techniques in ranking: Improving the Materials Selection process in engineering design
Materials & Design, 2015Co-Authors: Ali Jahan, K.l. EdwardsAbstract:Abstract Considerable effort has been spent on the development of normalization models in multi-attribute decision-making (MADM) but despite all of these there is no definitive answer to question: which technique is the most appropriate? Therefore, after a thorough review of the literature, thirty-one methods were identified, classified and evaluated for use in Materials Selection problems. The objective of this paper is to examine the shortcomings of normalization methods and suggest ways of improving their use in the engineering design decision-making process. The emphasis is placed on Materials Selection, for problems that include target criteria, as well as cost and benefit considerations, typically seen in more challenging applications such as aerospace and biomedical engineering. It is shown that although many normalization methods may appear to be minor variants of each other, these nuances can have important consequences in engineering design decision-making. To conclude, some dimensionless methods are proposed. The result of this research investigation will help ensure engineering decision makers in general improve their current use of MADM methods but in particular aid designers in developing suitable design performance indices for Materials Selection.

multi criteria decision analysis for supporting the Selection of engineering Materials in product design
2013Co-Authors: Ali Jahan, K.l. Edwards, Marjan BahraminasabAbstract:Multi-criteria Decision Analysis for Supporting the Selection of Engineering Materials in Product Design, Second Edition, provides readers with tactics they can use to optimally select Materials to satisfy complex design problems when they are faced with the vast range of Materials available. Current approaches to Materials Selection range from the use of intuition and experience, to more formalized computer-based methods, such as electronic databases with search engines to facilitate the Materials Selection process. Recently, multi-criteria decision-making (MCDM) methods have been applied to Materials Selection, demonstrating significant capability for tackling complex design problems. This book describes the rapidly growing field of MCDM and its application to Materials Selection. It aids readers in producing successful designs by improving the decision-making process. This new edition updates and expands previous key topics, including new chapters on Materials Selection in the context of design problem-solving and multiple objective decision-making, also presenting a significant amount of additional case studies that will aid in the learning process.Describes the advantages of Quality Function Deployment (QFD) in the Materials Selection process through different case studiesPresents a methodology for multi-objective material design optimization that employs Design of Experiments coupled with Finite Element AnalysisSupplements existing quantitative methods of Materials Selection by allowing simultaneous consideration of design attributes, component configurations, and types of materialProvides a case study for simultaneous Materials Selection and geometrical optimization processes

A target-based normalization technique for Materials Selection
Materials & Design, 2012Co-Authors: Ali Jahan, Marjan Bahraminasab, K.l. EdwardsAbstract:Abstract Ranking and Selection of the optimal material is an important stage in the engineering design process. However, most of the methods proposed for ranking in Materials Selection have tended to focus on cost and benefit criteria, with target values receiving much less attention in spite of their importance in many practical decision-making problems such as selecting Materials to best match the properties of human tissue in biomedical engineering applications. In response to this perceived gap, the development of a new normalization technique is considered in this paper that provides an extension of the Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) method and objective weighting in Materials Selection. There are four example cases included to validate the accuracy of outcomes from the proposed model. It is believed that the proposed decision-making model is suitable for linking to material databases and has the potential to enhance the efficiency of computer-aided Materials Selection systems.

Design, Materials Selection and marketing of successful products
Materials & Design, 2003Co-Authors: Lennart Y Ljungberg, K.l. EdwardsAbstract:There are many things that make products successful in the market place. This paper is a comprehensive tool for understanding how to develop products with special respect to integrated product development. Materials Selection, marketing and design analysis in the form of a design manual are presented as a tool for the product developer. Many different methods for Materials Selection and design have been presented over the last couple of decades. However, most methods have been limited to the material as a physical entity to give shape for a product. The method presented in this paper is an approach to present a Materials Selection model that is an integral part in an integrated product development model, in which both physical and metaphysical properties are analysed for different types of products. The new integrated product Materials Selection (IPMS) model presented incorporates factors such as fashion, market trends, cultural aspects, aesthetics and recycling, as well as the target group. Interesting examples of successful product contra failures are presented, as well as examples of Materials Selection for different products. Different methods for Materials Selection are discussed and analysed with respect to the IPMS method presented.
