Abstract :
In this research work, shell and tube type heat exchanger has been designed by KERN method.
To eliminate design problems, computer software (DSTHE software) has been developed. All
design parameters have been calculated by this method with the help of DSTHE software like
number of tubes, shell diameter, pipe pitch, pitch ratio etc. and then velocity of the tube side
fluid, convective heat transfer coefficients for tube and shell side fluids and overall heat transfer
coefficient have been calculated. By developed DSTHE software, tube side and shell side fluids
pressure drops, entropy generation and entransy dissipation have also been found. Shell and tube
type heat exchanger has been fabricated with calculated parameters. At various operating
conditions, numbers of experiments have been performed. For each condition, entropy

generation analysis, entransy dissipation analysis and entransy based thermal resistance analysis
have been done. Maximum value of effectiveness, minimum values of entropy generation,
entransy dissipation and entransy based thermal resistance have been found and that actual
operating conditions have been identified.
