毛细管内气泡变形及脉动运动模拟
SIMULATION OF BUBBLE DEFORMATION AND PULSATING MOVEMENT IN CAPILLARY
摘要
Abstract
The movement and deformation of the bubbles in capillary are analyzed by VOF model combined with CSF model.Taking viscous force, inertial force and surface tension effect into consideration, we proceed numerical calculations of the deformation of different bubbles' diameters in capillary and achieve the result that bubbles break into a bubble flow through the form of circle, bullet shape and arrow shape.Then, we proceed a numerical simulation when the bubbles in capillary burst while moving.The result shows that there all exist a critical value of capillary rupture.Finally, we apply a pulsating load on both sides of the capillary and analyze the situation of bubble movement under pulsating load.We achieve that pulsating movement of bubbles in capillary comes to be more vigorous with the increasing pulsating pressure wave, and the bubble's shape also changes periodically with the pulsating of pressure.关键词
