| 摘 要： | 采用计算流体力学方法对除雾器内流场进行数值模拟.除雾器内气液两相流动的数值计算主要用基于欧拉-拉格朗日方法的离散相模型.流体被当做连续相,其流场可通过时均N-S方程求得,而离散相液滴的轨迹则可通过已经计算的流场追踪得到.通过计算不同工作参数下除雾器的除雾效率和压降,分析并总结了不同参数对除雾效率和压降的影响规律,对除雾...

| Abstract: | The computational fluid dynamics method is used to simulate numerically the flow field of the demister.The discrete phase model based on Euler-Lagrange approach is used to simulate numerically the gas-liquid two phase flow in a demister.The fluid phase is treated as a continuous phase and it's flow field can be obatined by Navier-Stokes equations,while the dispersed phase droplets trajectories can be got by tracking the calculated flow field.By calculating the demisting efficiency and pressure drop of demis... |
