Summary

A parametric study was conducted for radial Reynolds numbers of 0.01, 4, and 20, and rotational speeds ranging from 0 to 2,800 revolutions per minute. The numerical results indicate that the pressure and the axial, radial, and tangential velocities are significantly affected by the rotational speed and the radial Reynolds number. In comparison to non-rotating heat pipes, the radial pressure distribution is no longer uniform. Above a certain rotational speed, flow reversal occurs near the centerline of the heat pipe. The results of the study will be beneficial in the prediction of the performance of axially rotating heat pipes.
