... Acoustic Streaming in a Cylindrical Tube . ... There is no restriction on tube radius in relation to boundary layer thickness. ... Only the inner vortex is observed when tube radius is comparable to boundary layer thickness, such as within the channels in thermoacoustic engine stacks. Both vortices are prominent for intermediate tube radii. Thermal conductivity is found to increase streaming velocity, while dependence of the viscosity coefficient on temperature partly offsets this increase. ...
