Numerical Investigation For Convective Heat Transfer and Friction Factor Under Pulsatile Flow Conditions

Erman Aslan [1]

Under pulsatile flow conditions, the characteristics of convective heat transfer and friction factor for periodic corrugated channel are investigated numerically. The Finite Volume Method (FVM) is used in the numerical study. Three different Reynolds Averaged Numerical Simulation (RANS) based turbulence models, namely the k-ω, the Shear Stress Transport (SST) and the transition SST model are employed and compared with each other. The results are also compared with the previous measurements performed for non-pulsating conditions. Investigations are performed for air flowing through corrugated channel which has sharp corrugation peak with an inclination angle of 30° and a 5mm minimum channel height. Reynolds number is varied within the range 6294 to 7380, while keeping the Prandtl number constant at 0.70. Four different sinusoidal pulsatile flow conditions, which are combination of two different frequencies and two different amplitudes, are used. Variations of the Nusselt number and friction factor with the Reynolds number are studied. Effects of the amplitude and period of sinusoidal pulsatile flow conditions are discussed.
