Numerical analysis for flow and heat transfer in new shapes of corrugated channel

الملخص EN

Present study numerically investigates the flow field and heat transfer in two dimensional new shapes of corrugated wall channels.

Simulations are performed for fully developed flow conditions.

The governing continuity, momentum and energy equations are numerically solved using finite volume method based on SIMPLE technique.

The investigation covers Reynolds number in the rage of 200-1400.

The effects of Reynolds number and varying (LR / LL) ratio from 0.28 to 3.6 are studied for keeping wavy wall wavelength (Lw) value and distance between triangle in corrugated channel (d) fixed for all shapes.

The results show that heat transfer enhancement increases by using corrugated channel and also, heat transfer increases and vortices are decreases with decreasing the value (LR / LL).
