Abstract

Heat exchangers are one of the most important devices of mechanical systems in modern
society. Most industrial processes involve the transfer of heat and more often they require
the heat transfer process to be controlled. A heat exchanger is the heat exchanged between
two media, one being cold and the other being hot. There are different types of heat
exchanger, but the type which is widely used in industrial application is the shell and tube.
In this study, experiments conducted based on fully replicable five-factor, five-level central
composite design. Regression modelsare developed to analyse the effects of shell and tube
heat exchange process parameter such as inlet temperature of hot fluid and flow rates of
cold and hot fluid. The output parameters of a heat exchanger are used for analysing the
direct and interactive effects of heat exchange process parameters.
