Abstract:
A numerical and experimental study has been carried out
on the heat transfer and fluid flow in a PHE. By means of a
high-performance computing cluster, large-size and nosimplified
plates can be simulated with 67 million
computational cells. A new approach providing a proper
clearance between two adjacent corrugated plates is proposed
to improve the mesh quality around the contact points. The
clearance value and the influence on the mesh quality and
computational results are carefully studied. The results show
that the ratio of clearance c to equivalent diameter De equals to
0.02 is proper. The CFD results agree with the experimental
results with an error less than 10%. The proposed approach is
proved to be effective and practical because it can increases the
grid quality without losing the accurate of the results. This
paper shows that CFD is a reliable tool for studying effect of
various geometrical configurations on the optimum design of a
PHE.
