Abstract

Abstract: The calculating formula of flow resistance of heat exchanger with longitudinal fluid flow on shell side is derived by the method of regarding zero shear stress line as separate boundary of tube unit. The parameters are derived by experiment , and the variations of flow resistance correspond with experiment data . The maximum deviation with experimental data is less than 6% .
