Modelling of droplets evaporation in ejector heat exchanger.

In process of industry development load of an environment grows. The problem of creation of effective methods of purification of flue gases acquires the increasing relevance. The scheme of the refrigerator with the ejector heat exchanger is provided. The solution of this question is proposed in use of the refrigeration unit with the heat exchanger ejector. Cooling of a gas flow is carried out due to injection of finely divided drops in the dispersed gas flow in the heat exchanger the ejector. In the field of subsonic speeds at this process it is possible to increase the total pressure of a flow.

随着工业发展进程的推进，环境承载负荷日益攀升。开发高效烟气（flue gases）净化方法的相关问题，其重要性与日俱增。目前已提出一种搭载喷射式换热器（ejector heat exchanger）的制冷系统方案。针对上述问题，本文提出采用搭载喷射式换热器的制冷机组作为解决方案。该方案通过向分散气流中喷射微细液滴，在喷射式换热器内实现气流冷却。在亚音速工况下开展该流程时，可提升气流的总压（total pressure）。
