Effect of Geometric Parameters on Mass Transfer Characteristics for Pulsatile Flow in Wavy-Walled Tubes

Abstract:

In the experiment, three kinds of wavy-walled tubes with different wave factor F_w were applied to study the effect of geometric parameters on mass transfer characteristics. Results show that mass transfer characteristics are influenced significantly by the oscillatory frequency and the wavelength of the wavy-walled tube. The peak value of the mass transfer enhancement is obtained at the multiple order oscillatory frequency, and the effective mass transfer enhancement is occurred when the wave factor F_w = 0.58. For the same Re number, the mass transfer enhancement factor E increases with the oscillatory fraction P, and the optimal Strouhal number St corresponding to different peak E almost does not change with P.
