Heat transfer. Using MathCAD to calculate the heat transfer processes

0

The Scientific Publications Division of the Institute of Aviation has published a book “Heat transfer. Using MathCAD to calculate the heat transfer processes” by professor Roman Domański. The book has been released as part of the Scientific Library of the Institute of Aviation series.

Energy and its conversion processes are the basis of our existence and the basis for the development of civilization. Heat energy transfer is therefore an important element in nature, technology and medicine. Heat transfer phenomena are very complex and their understanding is of fundamental importance for the development of new technologies. Experiments with heat transfer are difficult and expensive, and the theoretical solutions are possible for simple geometries and boundary conditions, so simulations and numerical calculations are important.

The dynamic development and miniaturization of microchips allows for a significant increase in computing power and therefore an increase in the importance of numerical calculations. We have many professional programs on the market that can be used to calculate heat transfer processes, eg. Mathematica, Maple, Derive, Matlab, also Fluent and ANSYS. One of the tools is a MathCAD program. The lecture is fully prepared as a set of programs in MathCAD, which also serve as a guide and calculation tool. The basic issues of heat transfer with examples of calculation are prepared in this way. A user can change the input data, selected geometric and material parameters and obtain results for cases of interest to them. In order to facilitate the understanding of calculations conducted in the MathCAD program, basic knowledge and equations in classical notation are presented before each chapter in a very compact way.

The paper presents a wide range of factors determining the configuration of radiation issues. In addition, a number of solutions for selected tasks involving complex heat transfer are presented.

The prepared set of programs can be very useful for engineers and students as it allows for quick, multi-variant calculations, eg. for ribs, transient temperature fields, or determining of heat transfer coefficients. The presented work is not a tutorial for the MathCAD program, but it contains examples of its application in the study of heat transfer processes. Drawings, due to the organization of the whole work, are numbered within the subsections within programs. It was not possible for reasons of maintenance requirements of programming to have the same designations throughout the paper. Some of the values required to initialize the program are not visible in the printout, but are visible in the MathCAD program. In some of the programs, units are not introduced and calculations are carried out for the current International System of Units.

These programs can provide help in learning the MathCAD program. In order to use the program, a user must install MathCAD 15 or a higher version with the converter. The handbook, of course, can be used as a classic book, and a great number of charts allow better understanding of physics problems. The study was based on the experience gained during the preparation of lectures, completing interim papers, diplomas and research projects. Registered users of the PTC MathCAD Prime 1.0 and a higher version have access to an earlier version, because the programs have not been converted to the Prime version. Two extended examples are shown in the Prime MathCAD 3.1. version. The study also included an appendix with the properties of the selected materials.

The book can be purchased in the on-line shop at this address.
