Abstract
A micro-thermocouple is specially designed and employed to measure the temperature distribution in the boundary layer around a cylinder surface, and the influence mechanism of rotation on the convective heat transfer characteristics from a large diameter rotating isothermal cylinder has been experimentally investigated. The effect of rotation on the trailing vortex is observed and analyzed by using a schlieren apparatus. The results show that rotation has an obvious effect on the air flow and temperature distribution characteristics around the cylinder surface. There exists a worst convective heat transfer region which does not coincide with the trailing vortex region as previously reported.
