On the effect of wall oscillations on mass (heat) transfer in channel flow
Copyright policy )On the effect of wall oscillations on mass (heat) transfer in channel flow
A mechanism is investigated which might lead to enhancement of the rate of mass (or heat) transfer in channel flow at relatively low Reynolds numbers. One of the possible areas of application of this mechanism concerns blood oxigenators. Enhancement of the transfer rate is sought by oscillating the channel walls. The mass transfer analysis given in this paper shows that, for large Peclet numbers and small amplitudes of the wall oscillations, the effect of the steady streaming can be exploited in order to increase mass transfer from the wall only for a range of moderate values of non-dimensional frequency \(\alpha\) close to 1.
