Thermal performance of plate heat exchangers with flow maldistribution, looped configurations.

Author(s) : HEGGS P. J., INGHAM D. B., SANDERSON P. D.

Summary

The thermal performance of an APV-HX6 plate heat exchanger is investigated for ten looped configurations where the ratio of flowing heat capacities is equal to 1. The thermal performance of the exchanger is described by the thermal effectiveness, which is obtained by carrying out enthalpy balances along the outlet manifolds of the plate pack. Results have shown that the effectiveness reaches an asymptotic value as the number of channels increases. Where the flowing heat capacities are flowing in opposite directions along the entire length of the plate pack, the effectiveness increases to a maximum value and then decreases as the number of channels increases. An exception to this phenomenon is described and explained.
