COMPUTER AIDED DESIGN OF SHELL AND TUBE HEAT EXCHANGER

Abstract

ABSTRACT The computer aided design (CAD) is a utility that enables the speedy processing of design procedure and calculations. This eliminates the rigour encountered and associated with manual calculation. CAD, is such that, it is programmed to evaluate on the physical properties needed, which would have taken manual design a signi ficant time in interpolating, extraplating and interpreting data from curves, monographs or tables. For this particular project, the design of a shell and tube heat exchanger was carried out with the aim to develop a program that can perform the rigorous and tedious calculation needed in the design, simulation and optimization of a shell and tube exchanger. For the design, a problem was taken from a certi tied literature (Richardson and Coulson Vol. 6), so to acertain the accuracy of the design. An assumed overall heat transfer coefficient was taken along side the other variables. At the end of the process, the values that were got by the computer process were similar to those calculated for in the literature. v
