With its comprehensive library of functions, the add-in enables Microsoft Excel to be used as a modelling platform for conducting parametric and optimisation analyses of advanced power generation and refrigeration cycles, airconditioning systems, and combustion processes. Developed with Microsoft VBA, the add-in provides property functions for ideal gases, saturated and superheated water, saturated and superheated refrigerants for vapour-compression (VC) systems, binary solutions of ammonia-water and water-lithium bromide for vapour-absorption (VA) refrigeration systems, reacting mixtures, and atmospheric air.

This paper presents an add-in that determines these properties for various fluids by using Microsoft Excel. However, relevant computer applications may not be available to many engineering students and practicing engineers particularly in developing countries. more Analyses of thermo-fluid systems require the thermo-physical properties of the working fluids to be repetitively determined at different conditions of pressure and/or temperature. The aim of this book is to complement the previous efforts by gathering the information needed for using Excel as an effective modelling platform for various types of computer-aided fluid-thermal analyses.Īnalyses of thermo-fluid systems require the thermo-physical properties of the working fluids to. However, a textbook that presents a general pedagogical approach for using Excel as a platform for computer-aided fluid-thermal analyses and provides the lecturers and students with sufficiently detailed examples and exercises has, so far, been missing. The lack of built-in functions for fluid properties also motivated a number of academic institutions and individual researchers to develop relevant Excel add-ins. With respect fluid-thermal analyses, a number of articles and research papers have been presented in this regard at various conferences and specialised publications over the past two decades. The powerful tools of Excel for data analysis and visualisation, together with its wide availability and simplicity, encouraged its use as an educational tool in various engineering subjects. more Microsoft Excel is a general-purpose application that is taught to engineering students in the introductory courses on computer applications. Microsoft Excel is a general-purpose application that is taught to engineering students in the in. The aim of this book is to illustrate the use of Microsoft Excel as a modelling platform for design analyses of fluid-thermal systems.

Although the use of computer-software for fluid-thermal analyses nowadays has become common place in the industry, the disadvantage of these dedicated applications for educational purposes is that they do not allow the student to develop their own analytical models from the basic principles apart from being expensive to acquire and require proper training to use. The analyses that deal with complex fluid-thermal systems, such as pipe-networks and heatexchanger networks, are best performed with the aid of computers which are also needed for design optimisation analyses of even the simple fluid-thermal systems like thermal insulation. A common reason is the need for iterative solutions because of the nonlinear equations involved or because of the inter-dependence between fluid properties and the imposed system forces, pressures, and temperatures. However, the application of these principles in design analyses of fluid-thermal systems requires computer-aided methods for various reasons. more The traditional approach of using hand-calculations with property tables and charts is an effective method for introducing the principles of thermodynamics, fluid mechanics, and heat-transfer to engineering students.
