Abstract

Numerical analysis is performed to find flow and heat transfer characteristics for ring type heat exchanger. 3-D numerical predictions are carried out for the ring type heat exchanger system with Reynolds number varying in the range of 1,000 and 10,000. From the prediction, streamwise velocity, pressure drop, flow rate and heat transfer coefficient are analyzed. It is also found that characteristics of pressure drop and heat transfer generally follow well proportional variations of Re$m^$for the wide range of Reynolds number considered in this study.
