摘要: 本文用MAC方法模拟了非牛顿流体介质如Maxwell流体下的淹没喷嘴产生的气泡生长的动力学过程,首次将此方法推广至有限区域内非牛顿流体介质下的淹没喷嘴气泡生长过程,成功地拓广了MAC方法的应用范围。

Abstract: The Marker-and-Cell technique is modified and generalized to the flow problems of non-Newtonian fluid, especially of viscoelastic fluid. The solution can be obtained for reasonably high elastic Deborah number. Discussions are also on the bubble formation and growth at the orifice submerged under the Maxwell liquid in finite extent, which is a typical problem incorporating varieties of complexity, including the non-sphericity of the bubble, the viscoelasticity of the liquid and the complex flow field.

Key words: MAC technique, Maxwell model, non-Newtonian, fluid flow, two-phase flow, bubbling flow
