Measurements of heat transfer from an isothermal rotating disk using a Mach-Zehnder interferometer
Abstract
Results are presented for the heat transfer from an horizontal disk rotating in still air. The investigation was carried out using a Mach-Zehnder interferometer, after the system was calibrated by verifying the empirical expression for an horizontal isothermal disk in natural convection. The results have extended the range of already known solutions, and experimental data, for rotational Reynold numbers below 10,000. The orientation of the rotating disk, appears to have no effect on the heat transfer, which is of the mixed convection mode.
