Heat transfer enhancement in three-dimensional corrugated channel flow

Flow and heat transfer characteristics in a channel having furrowed wall based on sinusoidal wave

“…The equations describing turbulent flow and heat transfer are given by the conservation of mass, momentum and energy. In large eddy simulation, filtered forms of the continuity and momentum equations for incompressible fluid are expressed as follows: (1) (2) where and are filtered velocity, filtered pressure and subgrid-scale stress tensor, respectively, the indices i, j refer to the directions of coordinates. The subgrid-scale stress tensor is defined as = − .…”

“…Many investigations have indicated that the modified geometrical surface can strengthen the disturbance in boundary layer. Sawyers et al [2] numerically studied the effect of three-dimensional laminar flow hydrodynamics characteristics on the steady-state heat transfer enhancement of corrugated channels. Naphon [3] investigated the heat transfer performance and pressure drop of the channel with V corrugated upper and lower plates.…”

A CFD study on turbulent forced convection flow of Al2O3-water nanofluid in semi-circular corrugated channel

“…Various numerical and experimental studies on the forced convection flow of conventional fluids or nanofluids in channels exist in the literature [1][2][3][4][5][6][7][8][9][10][11][12]. Sunden and Skoldheden [1] experimentally studied the heat transfer and pressure drop in corrugated channels and smooth tubes.…”

“…Sunden and Skoldheden [1] experimentally studied the heat transfer and pressure drop in corrugated channels and smooth tubes. Sawyers [2] numerically and experimentally studied the effect of three dimensional hydrodynamics on the enhancement of heat transfer in corrugated channels for Reynolds numbers in the range of 9-149. Fabbri [3] studied laminar convective heat transfer in a channel composed of smooth and corrugated walls.…”

Three dimensional numerical investigations on the heat transfer enhancement in a triangular facing step channels using nanofluid

“…Many experimental studies of convective heat transfer of conventional fluid in corrugated channels at laminar flow condition have been carried out in the past [6,7,8,9]. Rushet et al [10] experimentally performed the study on the heat transfer and flow characteristics under sinusoidal wavy laminar flows through a channel.…”
