1.A review has been undertaken of the development of main turbulent models which include turbulent transport models and large eddy simulations. It has been concluded that the k-εturbulent model is one of the best for indoor air movement predictions.
本文论述了紊流输运模型和大涡旋模拟等主要紊流模型的发展概况,指出k-ε紊流模型是用于室内气流分布模拟的最好模型之一。收藏指正
2.Modeling solid-liquid interaction flows is complex. Liquid phase transport equations coupled with the solid particles interaction are derived based on the RSM turbulent models to handle the interaction of momentum and kinetic energy of turbulence between the liquid and solid particles,in this thesis DPM models and stochastic trajectory models are adopted, and join the source of particles influence at the base of turbulence models, summarize the movement track and separation efficiency while different diameter particles in different displacement enter the hydrocyclone.
固-液两相流的模拟是在液相流场计算的基础上,采用DPM模型和涉及湍流扩散影响的随机轨道模型,同时在湍流模型中加入了颗粒影响的源项,总结了不同直径的颗粒在不同入口位置进入旋流器后的运动轨迹和颗粒分离效率。收藏指正
