Experimental Technique for Heat Transfer Measurements on Fast Moving Sprayed Surfaces

Popis výsledku v původním jazyce

Experimental technique for the measurements of heat transfer distribution at spray cooled surfaces is described. The measurements were done at moving surfaces up to a velocity of 12 m/s. The samples of different cross sections (flat, profile, rail, etc.)can move linearly. Different approaches are used for the measurements of heat transfer coefficient (HTC) distribution or heat flux distribution at rotating cylindrical body. The results of HTC distribution for spray cooling are shown and are compared towater impingement density. Influence of water impingement density, water pressure, spray configuration and surface velocity is studied. Examples for water nozzles and for mist nozzles (water-air) are given. Emulsions and oils are beneficial for some industrial applications of spray cooling. The cooling experiments performed with these liquids provide information about decrease of cooling intensity even for a low concentration of the oils in water. The results comparing the cooling prope
