Approximate Solution for a Nonisothermal Gas Bubble Growth over a Spherical Heating Element

摘要: Recent experimental evidence has shown that single bubble generation on miniature heating elements is a competitive alternative to massive bulk for the study of gas/ vapor growth dynamics. The inherent two-dimensionality problem leads significant deviations with respect which can be approximated by classical one-dimensional (spherically symmetric) theory. In present work, an approximate theory developed, valid certain region parameters, permits computation radius evolution curves. On basis these results, effect (axial symmetry) characteristics assessed. solution developed here particular interest, since complete using computational fluid dynamics (CFD) techniques not practically feasible at this moment because large number size and time scales involved in problem.
