The use of liquid films flow offers solutions for the problems associated with the microgravity applications. The thermal entry length of laminar wavy falling films was experimentally determined under full gravity conditions by means of infrared thermography. A dependence of the entry length on the Reynolds, Prandtl, and Kapitza number as well as the ratio Pr0/PrW between the Prandtl numbers at inflow and wall temperatures was found.
