Modelling and simulation of thermal and hydrodynamic performance of heat exchangers for automotive applications. 2. Evaporators.

Author(s) : MATHUR G. D.

Summary

A program has been developed to optimize the performance of finned tube condensers and to predict the thermal and hydrodynamic performance of finned tube evaporators. The model is based on a steady-state finite difference model. The correlations for predicting the heat transfer and pressure drop are used from the literature. Experimental test data are used to validate the developed model for a finned tube evaporator with R12 as working fluid. 66% of the total heat transfer area is occupied by flow boiling; 23% by the dryout region and 11% by single-phase vapor flow.
