This study is concerned with heat transfer to liquid films flowing across the surface of a rotating disc. Sensible heat transfer of the liquid film is investigated using water as a test fluid. A model for the thermal performance of such devices has been constructed and compared for water at different feed rates and speed of rotation. The effect of feed rate and disc speed on the experimental calculations and its relation to predicted model has been studied. The model has been tested under wide range of operating conditions and comparison between measured and predicted heat transfer rates is quite good.
