The dynamics of vapor bubble growth in boiling owing to excess enthalpy of surrounding superheated liquid

The formula of exponential time dependence of the radius of spherical bubble is derived. The parameters of this formula are determined for the first time as a result of theoretical analysis. The known experimental data, obtained under conditions of boiling in a body of liquid, on a thin wire, and on a flat surface, are used to demonstrate the much higher accuracy of approximation of these data by the exponential dependence compared to other, most frequently employed, formulas.
