METHOD FOR DETERMINATION OF DENSITY OF CENTERS OF STEAM FORMATION AT LIQUID BOILING ON OUTER HEATING SURFACES

摘要

The invention relates to investigation of heat exchange at boiling of liquids on surfaces of heat exchange devices where process of boiling at cooling is used (nuclear industry), at evaporation (chemical industry) and others. The method for determination of density of centers of vapor formation at liquid boiling on outer heating surfaces is based on problem of improvement of accuracy of determination of density of centers of vapor formation at boiling of water and water solutions that always have in their content dissoluble salts that are deposited on surfaces of boilers. Determination of centers of vapor formation is realized through calculation of well seen rounded spots on polished surface of heater.
