Краткое описание

Vortex structures and streamline patterns of turbulent flow in a single cross-corrugated channel of a circular plate heat exchanger have been investigated using RANS and hybrid URANS-LES methods. For validation simulations of a simplified plate heat exchanger model have been performed and compared to experimental data.
RANS simulations have shown that the fluid is homogeneously distributed over the circular plate due to the high flow resistance of the surface geometry. The flow structures gained by the hybrid model consist mainly of small eddies and large vortex tubes arising at the contact points. This leads to well mixing of the fluid.
