Abstract
In a method of determining the rate of heat transfer from a surface due to liquid convection, a coating of a material capable of dissolving in the convecting liquid and whose optical properties on irradiation are proportional to the thickness of the coating, is applied to the surface and is then exposed to radiation and to the convecting liquid, the change in the amount of radiation transmitted or reflected from the coating giving an indication of the rate of heat transfer.
