Fluid flow and mass transfer enhancement were investigated numerically with the software Fluent in a sinusoidal wavy-walled tube for pulsatile laminar flow,and the comparison between numerical and experimental results was performed.Three parameters were considered here:net flow Reynolds number,oscillatory fraction of flow rate and Strouhal number.Among them,the effect of Strouhal number was especially investigated.The numerical results of flow patterns and mass transfer enhancement below the moderate Reynolds numbers showed that there existed an optimum Strouhal number corresponding to the maximum mass transfer enhancement effect,and a good agreement was found between numerical and experimental results.
