The entrance effects at a stacked screen heat exchanger are investigated with two CFD test cases. The first CFD test case models an ideal heat exchanger adjacent to an open space. The influence of the heat conduction on the mean temperature is shown. The second test case models two screens of a stacked screen regenerator as two inline cylinders. The mean temperature profile is compared to the numerical solution of a reduced model equation. It is shown that viscous effects do not influence the mean temperature profile at low amplitude.
