Computation of Nusselt numbers in plate heat exchangers using CFD with Reynolds-averaged Navier–Stokes equations

Abstract

A CFD simulation based on a Reynolds-averaged Navier–Stokes model is employed to compute Nusselt numbers in corrugated plate heat exchangers. The approach is verified via the Dittus-Boelter formula in a simplified tube geometry. A corrugated plate is analyzed and the effect of a chevron angle on the Nusselt number is investigated.
