摘要
本文针对汽水分离器均匀流场中单个液滴的运动机理进行研究,分析了液滴在蒸汽流中所受的力;建立了单个液滴运动模型,并进行了数值求解;分析了其主要参数对液滴运动轨迹的影响,包括蒸汽流速、液滴直径和初速度等。定性描述了蒸汽流场中液滴重力分离之机理,为单液滴动力学模型定量分析奠定了基础。
A physical description of the formative cause and mechanism of the droplets movement in the steam uniform flow field in the separator was researched in the paper. According to the mechanism of gravity separation, the forces on droplets were analyzed and the equation of single droplet was founded and solved. The effects of the velocity of the vapor flow,the droplet diameter, the initial velocity as well as the gravity separation space height,on the gravity separation efficiency were discussed in details. The mechanism of the droplets movement and separation qualitative analysis will set up the groundwork for the qualitative analysis of the dynamic single-drop model.
