Effect of corrugated plates in an in-phase arrangement on the heat transfer and flow developments

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

“…In addition, by decrease of nanoparticle diameter, the Nusselt number increased. The results of the present study are consistent with the results presented by [7], [8], [9], [10], [11] and [12]. Finally, higher Nusselt number enhancement ratio which indicates the optimum configuration is 2.07 at Reynolds number 30000 and volume fraction 6%.…”

Design characteristics of corrugated trapezoidal plate heat exchangers using nanofluids

“…The use of a corrugated channel result in a more complex flow structure and improves the heat transfer by twice or thrice as much as that of a conventional straight channel [16][17][18][19][20][21][22].…”

“…1, the k-ε standard turbulence model [20] was used to simulate the turbulent heat transfer and flow characteristics. The main governing equations [43] can be written in the following form:…”

“…The turbulent kinetic energy, in k and the turbulent dissipation in , at the inlet section are approximated from the turbulent intensity, I [20,44]. The turbulent characteristic length, Lt , is:…”

Numerical Analysis of Flow Field and Heat Transfer of 2D Wavy Ducts and Optimization by Entropy Generation Minimization Method

“…Metwally and Manglik [17] simulated the laminar periodically developed forced convection in sinusoidal corrugated-plate channels by using the control volume finite-difference method. Naphon [ [18][19][20] experimentally and numerically studied on the heat transfer characteristics and pressure drop in the corrugated channel with different wavy angles and channel heights. Gradeck et al [21] observed flow patterns of a gas-liquid flow and analyzed heat transfer in horizontal corrugated channels by using nitrogen and water as working fluids.…”
