长期以来，对喷雾干燥过程进行了各种试验和模拟研究，但这些研究并不能揭示喷雾干燥室内气体运动状态，颗粒群的运动轨迹和各种热力学参数分布信息，常规的测试手段又很难测得，而这些参数分布信息对干燥器没计和过程优化具有重要指导作用。 - ( 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。
