摘要
对适用于高温高压下的一种新型旋风分离器的气相流场用粒子动态分析仪(PDA)进行了测试。并且用计算流体力学(CFD)软件中的不同湍流模型对其流场进行了数值模拟,得出了该旋风分离器不同的结构和操作条件对其流场的影响规律,同时也找到了适合模拟该种旋风分离器流场的湍流模型——雷诺应力模型(RSM)。
The flow field in a new cyclone-type separator which adapt for high temperature and high upressure was studied experimentally by using particla dynamic analyser (PDA) and simulated numerically by using Computational Fluid Dynamic (CFD) software with different turbulent models. The effects of different structural parameters and operational conditionson on the flow field were obtained. The appropriate turbulent model for the simulation was found being reynolds stress model.
