Теплообмен при кипении на оребренных горизонтальных трубах в условиях свободного движения

Abstract

The effect of finned surface geometry on the heat exchange rate during acetone and ethyl alcohol boiling has been investigated The ex­ periments were conducted under free motion conditions at the atmospheric pressure within the range of heat flow q = 8 - 63 kW/m! . Semi- empirical criteria! equations have been obtained which permit to calculate heat exchange rate during acetone and ethyl alcohol boiling on the finned surface under investigated conditions.
