摘要：
Present study deals with three-dimensional numerical investigations on flow and heat transfer characteristics of sinusoidal wavy channel with secondary corrugations. Computations are carried out by using commercial software ANSYS Fluent 17.2 by considering different wave amplitudes and number of waves in streamwise as well as spanwise directions for fixed width and height of the channel. Flow and heat transfer characteristics of secondary corrugated channels are compared with channels having spanwise and streamwise corrugations alone. Flow characteristics are explained with the help of streamline plots. Volume weighted-average values of secondary flow intensity have been shown to demonstrate the strength of secondary flow generated in different corrugated channels. Effect of secondary flow on heat transfer characteristics has been explained with the help of field synergy principle.
