Abstract
A method of determining the rate of heat transfer from a surface due to fluid convection, in which a sheet of liquid absorbent material, whose transmissive or reflective properties for certain radiations vary with the liquid content, is attached to the surface and, after being wetted with a liquid which will evaporate on passage of the convective fluid, the sheet is exposed to the radiation and to the convecting fluid, and the change in the amount of radiation transmitted through or reflected from the sheet is monitored, this giving a ready indication of the rate of heat transfer.
