Abstract : The choice of heat fluxes in newly designed devices cannot be accomplished without knowing the magnitudes of the critical heat fluxes. Most of the existing quantitative relationships are based on data from experiments with water, studies of organic carriers are not very numerous. The present experiment used the procedures and experimental devices described earlier by the authors and studied 95.6-96.0% pure ethyl alcohol. An analysis of the various results shows that within the investigated range of values the size of the tube does not affect the magnitudes of the critical heat flux. It is also found that none of the formulas proposes by various Soviet authors can be used for the determination of the critical flux values for the surface boiling of ethyl alcohol in tubes.
