摘　　要：采用mixture模型,应用有限体积法,对一简易船型在船首底部喷射微气泡,进行微气泡减阻的数值模拟。计算中考虑气泡与水之间相对运动的影响,分析不同浮态下微气泡对减少船舶阻力的影响,获取了不同浮态时微气泡在船底的分布及流动情况。Numerical simulation of the micro-bubble drag reduction effect was carried out for a simple ship injecting bubbles from bilge of the vessel＇s bow, by the mixture model and finite volume method, considering the interaction of relative motion of bubbles and water. The influence of different floating state upon resistance reduction of micro-bubbles was analyzed. The distribution and movement of micro-bubbles in the bottom under different floating state was gotten.
