Abstract
Steady, two-dimensional, developing laminar forced convection is computed in channels of ten modules of three out-of-phase (symmetric) wall corrugations: sinusoidal-wavy-shaped (SWS), rounded-ellipse-shaped (RES), and rounded-vee-shaped (RVS). Different geometric configurations of the three shapes are studied. Fluid flow and heat transfer are examined in a typical module in the fully-developed region for Reynolds numbers in the range of 25 to 300 for a Prandtl number of 2.29. Over the ranges of the geometric parameters studied, the SWS corrugation has, in general, the lowest friction factor and highest average Nusselt number values. The RES corrugation has the highest heat transfer per unit pumping power at an inlet Reynolds number of 300.
