Longitudinal temprature changes in plate heat exchangers: analytical-numerical approach

10.22099/ijstm.2013.987

Abstract

The purpose of this paper is to develop analytical-numerical solutions to work out the longitudinal temperature changes of flow in the passages of a plate heat exchanger. The solution for a general variation in U, except for some special cases, becomes so complicated as to be impractical. In this regard uniform heat flux, constant U, linearity between U and T and linearity between U and T will be studied. The results are then compared with the established experimental data available in the literature using similar plate dimensions and flow details.
