- Kinetic model of particulate phase in dilute solid - liquid two - phase flows
低浓度固液两相流的颗粒相动理学模型 - ( 1 ) the cfd model for the pulse combustion spray drying process . the computational fluid dynamics ( cfd ) based on the two - phase flow theory was employed in this paper , which used the standard k - e model and the particle trajectory model to simulate the gas - particle flow in the drying chamber . the momentum , heat and mass transfer regarding both gaseous and particulate phases during the spray drying inside the drying chamber was also revealed
为解决这一难题，本文利用气体一颗粒两相流理论和计算流体力学( cfd )技术，建立了更符合实际喷雾干燥过程的数学模型即喷雾干燥的cfd模型，并进行了脉动燃烧喷雾干燥过程模拟，其主要内容如下： ( 1 )建立了脉动燃烧喷雾干燥的cfd模型该数学模型建立在气体一颗粒两相流基础之上，用标准k -模型预测干燥室内的气体湍流运动过程，颗粒轨道模型追踪干燥室内颗粒群的运动轨迹，热质传递模型描述空气和液滴的热质传递过程。 - The simulated profiles of flow field , temperature and humidity of the air phase , as well as particulate phase , in the drying chamber were showed . the simulation also showed that a large - scale vortex was observed in upper part of the drying chamber because of the unstable process of flow field and particle trajectories
通过模型的求解，得到了干燥室内气体运动状态，气体温度、湿度分布，颗粒运动轨迹，颗粒沿运动轨迹质量变化，颗粒沿运动轨迹的温度变化等各种动力学和热力学参数分布信息。
