FLOW LOSSES FOR HEAT EXCHANGERS WITH OBLIQUE FLOW HEADERS.
Abstract
The report presents the results of an analytical investigation and an experimental program of turbulent flow through a screen matrix oriented parallel to the main flow. Inlet and exit headers were shaped so as to keep the pressure difference across the matrix constant and thereby insure uniform flow through the matrix. The investigation is restricted to an overall parallel flow situation. Estimates of the pressure drop across the matrix and header arrangement are compared to experimental values. Measured static pressure profiles in the headers are also presented and compared to theoretical profiles. Estimates of the obtained matrix velocity profile are made on the basis of normal pressure differences. The report deals primarily with a single-pass, header-matrix arrangement; however an extension to a two-pass system is developed in order to determine the effect of flow with a non-uniform velocity profile entering the second inlet header on the overall pressure loss.
