气泡在剪切作用下的运动特性研究
Numerical research on bubble motion in shear flow
摘要
Abstract
The deformation dynamic characteristic of single bubble in shear flow was simulated by using the Boltzmann method based on the free energy model.Results show that the main axis of the bubble is always stretched while the mean axis and the minor axis are compressed when the bubble is subjected to shear flow.Furthermore, with the increase of the capillary number or the liquid-gas viscosity ratio, the deformation and deflection of bubble becomes severe.关键词
