Abstract
The two-dimensional thermal problem due to relative motion of a medium and a suddenly activated circular heat source is solved for several b oundary conditions. The solutions can be interpreted as for a moving h eat source in a stationary medium or a medium moving past a stationary heat source. Uniform and non-uniform temperature, and uniform and non -uniform heat flux boundary conditions are considered. The effect of v elocity and radial direction on the temperature distribution is examin ed. Average, steady-state Nusselt numbers are derived. The transient r esponse of a continuous line source is obtained as a limiting case of the prescribed heat flux solution.
