Abstract
Heat transport and pressure drop experiments were performed on oscillatory flow in a circular straight tube with a wire in its center. It seems to be possible that the axial heat transport increases by inserting a wire in a oscillatory flow field. The inserted wire increases the area of boundary layer around itself and it is also possible to play a role of artificial boundary layer. By increasing the area of the boundary layer, the radial heat transfer rate can be increased between the oscillating core flow with relatively high velocity and boundary layer flow with low velocity, which results in the enhancement of the axial heat transportation. The present experiments showed the promising results of axial heat transport enhancement by the insertion of a wire.
