ACTION OF VIBRATIONS ON HEAT AND MASS TRANSFER IN BOILING
V. F. Prisnyakov and K. V. Prisnyakov UDC 539.24 The state of the art of the works known in the literature and concerned with the influence of vibrations of structures of plants and artificially initiated vibrations in working liquids on the processes involving boiling is analyzed. The authors discuss theoretical and experimental results on the influence of frequencies and amplitudes on the internal characteristics of boiling, namely, the initiation of a vapor phase, the superheat in boiling, the growth and separation of vapor bubbles and the frequency of their occurrence, the density of nucleation sites, and also on the value of the heat fluxes and on the heat-transfer coefficient. Application of vibrational actions for intensification of heat- and mass-transfer processes is shown to be promising.
