Abstract
Three-dimensional flow and heat transfer in a rectangular miter-vend, with a 90° turn, were studied for the purpose of examining the effect of centrifugal force due to bending, in connection with a corrugated wall channel as a means of augmenting a forced-convection heat transfer with a single-phase flow in a heat exchanger. Analysis of the results is made for Reynolds number Re=10 to 600 and aspect ratio α=0, 0.5 and 1. Aspects of the flow and heat transfer characteristics are shown in terms of velocity vectors, path lines, intensities of secondary flow, wall pressure, wall shear stresses, local Nusselt numbers and cross-sectional mean Nusselt numbers.
