【摘要】 本文用边界元方法对弧心角2α诹不同值时弧形驱动空腔内 Stokes 流动进行数值模拟,数值计算方法可以数值模拟 R 和α取任意值时的流场,数值模拟的流场较 Hills 的数值结果更精确,适应性更强,特别是本文方法还可研究流动区域内的压力场以及边界面应力分布规律等。更多还原

【Abstract】 Stokes flow is simulated numerically within a wedge by a honing circular arc with boundary element method for arbitrary R(radius)and α(half-wedge angle),the numerical results are in good agreemant with previous analytical ones that shown the method is very effective and reliability in researching and solving Stokes flows within a wedge by a honing circular arc as R and α being varied.The question of especial importance is the method not only is more suitable for the arbitrary flow of a viscous fluid near a shape corner but also can suitable study the pressure on the boundary and in the flow region as well.更多还原
