Computer-Controlled Air-Conditioning Experimental Apparatus
Computer Applications in Engineering Education, 2009Co-Authors: Hosni I. Abu-mulawehAbstract:A portable Experimental setup for demonstrating air-conditioning processes was designed, developed and constructed by a multidisciplinary capstone senior design team. This Experimental Apparatus is currently being used to demonstrate to undergraduate students air-conditioning processes such as cooling, heating, and humidification. The level of cooling, heating, or humidification is being monitored and controlled using a PC-based control system which consists of LabVIEW and data acquisition unit. This article provides details about the integration of the electrical/electronic component and the control system. © 2009 Wiley Periodicals, Inc.

Development of a Bench-Top Air-to-Water Heat Pump Experimental Apparatus
International Journal of Engineering, 2009Co-Authors: Hosni I. Abu-mulawehAbstract:A bench-top air-to-water heat pump Experimental Apparatus was designed, developed, and constructed for instructional and demonstrative purposes. This air-to-water heat pump Experimental Apparatus is capable of demonstrating thermodynamics and heat transfer concepts and principles. This heat pump Experimental setup was designed around the vapor compression refrigeration cycle. This Experimental Apparatus has an intuitive user interface, reliable, safe for student use, and portable. The interface is capable of allowing data acquisition by a computer. A PC-based control system which consists of LabVIEW and data acquisition unit is employed to monitor and control this Experimental laboratory Apparatus. This paper provides details about the development of this unit and the integration of the electrical/electronic component and the control system.

A portable Experimental Apparatus for demonstrating the thermo-siphon heat recovery system concept
2006Co-Authors: Hosni I. Abu-mulawehAbstract:A portable thermo-siphon heat recovery system Experimental Apparatus was designed, developed and constructed for the undergraduate mechanical engineering laboratory at Indiana University-Purdue University Fort Wayne in Fort Wayne, USA. The purpose of this Experimental Apparatus is to demonstrate heat transfer principles and the concept of thermo-siphon heat recovery system. In this article, the author presents an Experimental set-up that will help undergraduate mechanical engineering students in understanding the basic heat transfer processes by utilising real life applications, such as using waste heat from a window type air conditioner to heat water for residential and commercial use. Heat recovery from an air conditioner by thermo-siphon is attractive because it eliminates the need for a circulating pump. This project was completed with the assistance of an Undergraduate Senior Project Grant from the American Society of Heating, Refrigeration, and Air Conditioning Engineers, Inc. (ASHRAE).

Portable Experimental Apparatus for Demonstrating Thermodynamics Principles
International Journal of Mechanical Engineering Education, 2004Co-Authors: Hosni I. Abu-mulawehAbstract:A refrigeration system for use as Experimental Apparatus was designed, developed and constructed. Its purpose was to demonstrate to mechanical engineering undergraduates the basic concepts of thermodynamics, such as the first and second laws. In addition, the Apparatus demonstrates a vapor compression refrigeration cycle. This paper presents a set of experiments in which the first and second laws of thermodynamics are employed to determine the heat gained by the refrigerant in the evaporator, the heat rejected from the refrigerant in the condenser, and the isentropic efficiency of the compressor. The objective of these experiments is to help students understand the basic thermodynamics processes by utilizing real-life applications.

Undergraduate mechanical engineering laboratory portable Experimental Apparatus for demonstrating heat recovery concepts
2004Co-Authors: Hosni I. Abu-mulawehAbstract:A portable wastewater heat recovery system Experimental Apparatus was designed, developed and constructed for an undergraduate mechanical engineering laboratory at Indiana University-Purdue University Fort Wayne, Fort Wayne, USA. The purpose of the Experimental Apparatus is to demonstrate heat transfer principles and heat recovery concepts. In this article, the author presents an Experimental set-up that will help the undergraduate mechanical engineering students in understanding basic heat transfer processes by utilising real life applications, such as a heat recovery system. This heat recovery system is a preheating unit for incoming cold water from residential and commercial (such as restaurants and hotels) hot water systems. It is designed to recover some of the heat of the wastewater flowing into the sewage system. This project was completed with the assistance of an Undergraduate Senior Project Grant from the American Society of Heating, Refrigeration and Air Conditioning Engineers (ASHRAE).

Scientists' Orientation to an Experimental Apparatus in Their Interaction in a Chemistry Lab.
Issues of Applied Linguistics, 1991Co-Authors: Maria EgbertAbstract:Author(s): Egbert, Maria M | Abstract: This study explores the relationship between scientists' orientation to one another and to an Experimental Apparatus, analyzing as data a videotaped authentic interaction among co-workers in a chemistry laboratory. It demonstrates how the scientists display systematic orientation to the Apparatus as their common spatial point of reference on the one hand and as the physical embodiment of the experiment on the other hand.

Study on Experimental Apparatus of thermal expansion characteristics of paraffin
Transducer and Microsystem Technologies, 2007Co-Authors: Liu Zhi-yongAbstract:In order to satisfy big output force and large stroke,paraffin is used as the material for the thermal-expansion-type microactuator in micro electro mechanical systems.An Experimental Apparatus for the measurement of thermal expansion characteristics of paraffin is designed and developed.The Experimental results indicate that paraffin has a large coefficient of expansion in the temperature range of 37~51 ℃,the ratio of the volume increase is or over 10 % and the output force is high.By mixing of several types of paraffin whose melting points(C atom)differ from each other,its melting point can be controlled in the temperature range of 30~70 ℃.This makes it possible develop a microactuator for use in endoscopic-surgery(as in human body).

Study on Experimental Apparatus for Thermal Expansion Characteristics of Paraffin
Manufacturing Technology & Machine Tool, 2008Co-Authors: Chen BingyaAbstract:In order to satisfy the big output force and large stroke, we use paraffin as the material for the thermal-expansion-type micro-actuator in micro electro mechanical systems. In this study we design and develop an Experimental Apparatus for the measurement of thermal expansion characteristics of paraffin. The Experimental results indicate that paraffin has a large coefficient of expansion in the temperature range of 37 to 51 degrees centigrade, the ratio of the volume increase is or over 10% and the output force is high. By mixing of several types of paraffin whose melting points differ from each other, its melting point can be controlled in the temperature range of 30 to 70℃. This makes it possible to develop a micro-actuator for use in endoscopic-surgery.
