Summary

EXPERIMENTS HAVE BEEN PERFORMED TO DETERMINE THE RESPONSE OF THE HEAT TRANSFER AND PRESSURE DROP ON THE SHELL SIDE OF SHELL AND TUBE HEAT EXCHANGER TO CHANGES IN THE INTERBAFFL THE GREATEST SENSITIVITYOF THE PER-TUBE HEAT TRANSFER COEFFICIENT TO THE INTERBAFFLE SPACING OCCURRED AT THE TUBES SITUATED IN THE INFLOW WINDOW OF A COMPARTMENT. IN THE CROSSFLOW ZONE, THE PER-TUBE TRANSFER COEFFICIENTS CORRESPONDING TO THE SMALLER INTERBAFFLESPACING EXCEEDED THOSE FOR THE LARGER INTERBAFFLE SPACING BY ABOUT 5%, AND SIMILARLY IN THE BAFFLE-ADJACENT ROW IN THE OUTFLOW WINDOW OF THE COMPARTMENT. THE COMPARTMENT-AVERAGE TRANSFER COEFFICIENTS WERE VIRTUALLY UNAFFECTED BY THE SPACING. THE PER-COMPARTMENT PRESSURE DROP DECREASED AS THE INTERBAFFLE SPACING DECREASED.
