Abstract

This paper numerically investigates to evaluate the performance according to the number of passes and the inlet/outlet diameter in a multi-pass multi-branch heat exchanger. A JF factor is used as an evaluation characteristic value to consider the heat transfer rate and the pressure drop simultaneously. It estimates the performance according to the number of passes and the inlet diameter of the reference heat exchanger. When the ratio of the inlet diameter to the header height is about 0.5, the optimum number of passes is selected along with the inlet diameter.
