重力场液滴旋转问题探究

Primary Investigation on Droplets Rotation in Gravity Field

对重力分离空间蒸汽流场单液滴旋转运动问题进行探究。根据液滴重力分离机理,采用考虑转动的单液滴模型,求解及分析了液滴在蒸汽流中受力、力矩及运动问题。描述了蒸汽流场及液滴旋转、液滴直径和速度等参数对于液滴轨迹的影响,为单液滴模型建立奠定了基础。

A single droplet rotation in the steam flow field in the gravity separation space was researched.According to the mechanism of gravity separation,the force and torque on droplet in steam flow were analysed and solved by employing the single droplet model taking into account rotation.The effects of droplet rotation,diameter and velocity as well as the vapor flow on droplet trajectory were described,laying the basis for establishing the dynamic single droplet model.
