A Review on Heat Transfer and Fluid Flow Over Wavy Channel or Surface

Abstract

Abstract-This paper concentrates to extensive review on the fluid flow and heat transfer over an wavy surface and channel. Wavy surfaces and channel have been employed in many environmental and industrial applications. The key factor for adopting such shaped (wavy) instead of using flat surface is due to improving the mass and heat transfer mechanisms, associated with large pressure variations. Fundamentally, the fully developed flow over a wavy surface, in either laminar or turbulent regime, is much further complex than that over a flat surface because of the additional parameters to be utilized and the correlated flow phenomena to be deduced. Numerous researches perform numericalcomputation simulations and experimentation in order to explore the flow characteristics over wavy surfaces are stated in this paper.
