An investigation of a compact heat exchanger unit using CFD with experimental support

Abstract

The paper contains a comparison of a numerical simulation with a real experiment. In the measured and simulated device is located a heat exchanger with a centrifugal fan. Due to the fan and the geometrical arrangement the flow is relative uneven and so the heat transfer hard to predict. The simulation should be time and cost affordable, so a standard k-ϵ turbulence model and a relative simple mesh was used for the computations.
