Abstract

Fluid flow and heat transfer in a two-dimensional miter-bend were examined 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. Pressure losses, distributions of mean velocities and velocity fluctuations, streaklines, power spectra of velocity fluctuation and local Nusselt number distributions were compared with those of numerical analysis. It is shown that the effect of heat transfer augmentation is remarkable on the Reynolds number of the order of 2000, where the laminar flow is maintained in the straight channel.
