| description | Numerical study on the mass transfer in a two-dimensional channel with the transversely oscillating wall was carried out as the basic study to understand the mass transfer of the infused drug into the blood flow. It is clear that the actual oscillation of the blood vessel in vivo includes the many frequency components with a wide range. So, the numerical calculations were carried out varying the wall oscillation frequency widely and we considered the role of the Strouhal number mainly. The calculation results are summarized as follows. (1) In a low Strouhal number region, the wall oscillation has an effect to enhance the mass diffusion. However, further increase in the Strouhal number brings the restraint effect of the mass diffusion and brings the increase in the mass concentration at the wall. (2) The increase in the Schmidt number has an effect to clarify the restraint effect of the mass diffusion in a high Strouhal number region. |
