ABSTRACT

Behavior of a single vapor bubble is studied under the conditions of bulk boiling. The relationship between the variable pressure generated by the bubble and thermal characteristics of the process are analyzed analytically. The cases of 0D, 1D, 2D and 3D oscillations of liquid particles are considered. The temporal functions of alternating pressure in the above cases, heat flux and its density via the bubble surface, the mean overheating in the thermal boundary layer are determined. These functions have been obtained using a specially developed approximations of the variations of bubble size. The results are presented in a generalized form.
