摘要
The paper presents temperature distribution of superheated liquid during the growth of spherical vapour bubble between two-phase temperatures. The heat equation is resolved by the modification of similarity parameter method of Screven [Chem Engng Sci 10:1-13(1959)] between two finite boundaries. Under these conditions, the growth of vapour bubble and temperature are obtained analytically in an implicit form which are different than that obtained before. The growth rate is obtained as a generalized formula compared with Plesset amd Zwick and Scriven et al. theories [J Appl Phys 25:493-500(1954);Chem Engng Sci 10:1-13(1959)]. The growth and temperature field affected by the initial superheating and thermal diffusivity.
