摘要

An analysis and a generalization are presented of experimental data on heat transfer and hydraulic resistance in tubes with smooth annular diaphragms of different geometrical shape(developed at MAI)that are arranged at regular intervals. It is shown that the greater the rounded radius of the diaphragms, the lower the coefficients of heat transfer and hydraulic resistance when the other parameters determining the efficiency of enhancing heat transfer remain unchanged.
