摘要
构建起旋涡框架下的气固两相流动数学模型与数值计算方法 :应用离散涡方法 (DVM)计算具有剧烈分离的非定常不稳定气流场 ,采用Lagrange方法模拟颗粒在流场中的运动 ;气流场的求解和颗粒运动求解 ,两者在时间上相互耦合 。
We present a numerical method for computing unsteady and unstable gas particle two phase flows.In the method,we apply the Discrete Vortex Method(DVM)to evaluate the unsteady and unstable gas flows and to adopt a Lagrangian approach to simulate the particle motion.In the process of the numerical simulation,the solution of gas flow field and that of particle motion are couple at each time step,so that the effect of unsteady and unstable flow is effectively accounted in simulation.
