Abstract

The present study focuses on the computation of fully developed flow and heat transfer through a stationary circular wavy-walled duct. The fluid temperature at the channel inlet (Tin) is taken less than that of the walls (Tw). The governing equations are numerically solved in the domain by the control volume approach based on the SIMPLE technique. The circular wavy channel of 2.0 m length are tested in the current work; the width (w) of the wavy channel is 0.1 m and different wave numbers (α = 6, 4, 2, 0) are used in the present computation. The laminar flow model is used for formulation, since the flow is laminar. A three-dimensional non uniform grid was generated, in order to critically examine the flow and heat transfer.  Computational results show that heat transfer in wavy duct can enhance up to certain percentage, depending on the value of α. It has been observed that the flow is strongly three-dimensional. The friction factor is found to be insensitive to the Reynolds number. Normalized Nusselt number ratio shows significant Reynolds number dependency.
