Dynamics of vapor bubbles growth at boiling resulting from enthalpy excess of the surrounding superheated liquid and sound pulses generated by bubbles

Hydrodynamics, thermodynamics, and acoustics of exponential growth of the vapor bubbles at saturated boiling

“…On its basis, the hydrodynamic, thermodynamic, acoustic dependences of the vapour bubble growth were obtained, and then the bound correlations of all these dependences were derived. This paper is a continuation and completion of the previous research [1][2][3][4][5][6][7][8][9][10][11][12][13][14].…”

“…In [1][2][3][4][5][6][7][8][9][10][11][12][13][14], an analytically rigorous derivation of the formulae of absolute values of variables presented in Table 1 on the left is presented: the radius of the vapour bubble, the velocity and acceleration with its growth, the specific and total heat flux through the interphase surface of the bubble, the liquid overheating and the heat transfer coefficient, sound pressure for one-and three-dimensional cases.…”

“…The exponential dependence of the vapour bubble radius on time was theoretically obtained in the study [1] in three different ways. This dependence with high accuracy (± 1%) is confirmed by the results of experiments with saturated boiling in the volume of liquid, on a thin wire and on a flat surface [2], and describes well the bubble growth at surface boiling of liquids [3].…”
