Abstract
In a computer-based design, many thousands of alternative exchanger configurations may be examined.
Computer codes for design are organized to vary systematically the exchanger parameters such as, shell
diameter, baffle spacing, number of tube-side pass to identify configurations that satisfy the specified heat
transfer and pressure drops. A computer-based design model was made for preliminary design of shell-andtube
heat exchangers with single-phase fluid flow both on shell and tube side. The program covers segmentally
baffled U-tube, and fixed tube sheet heat exchangers one-pass and two-pass for tube-side flow. The
program determines the overall dimensions of the shell, the tube bundle, and optimum heat transfer surface
area required to meet the specified heat transfer duty by calculating minimum or allowable shell-side
pressure drop.
