METHOD FOR DETERMINATION OF COEFFICIENT OF HEAT EMISSION UNDER CONDITIONS OF CONVECTIVE HEAT EXCHANGE OF ORGANIC MIX

摘要

Method for determination of coefficient of heat emission under conditions of convective heat exchange of organic mix that includes measurement of temperature of heat carriers, at that one measures the mass of heating heat carrier and mix, and temperature of heating heat carrier and mix are measured through time intervals with determination of experimental coefficient of convective heat emission in basic mode of heat exchange at temperature of mix that corresponds to the modes looked for, and the complex of physical properties for basic mode of heat exchange is determined by dependence, with account of direction of heat exchange. Due to more accurate selection of model liquid and its parameters, and use of its thermo-physical properties, possibility is achieved for correct determination of the mode of heat exchange looked for, through set of physical properties for basic mode of heat exchange, this leads to decrease of error of determination of experimental-calculated looked for coefficient of heat emission and increase of effectiveness of heat exchange equipment.
