| Abstract: | 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. |
