ABSTRACT Complex non-steady flow processes and induction mechanisms in pressure-exchange ejectors will be investigated. The goal of the proposed work is to establish performance characteristic and design information that will allow the technology to be used in ejector refrigeration systems. The research will have an experimental phase to determine the optimal design of the rotor, diffuser, and the nozzle in the ejector. Theoretical and computational analyses will also be carried out to study the flow behavior inside the ejector. Results from the theoretical study will be used to guide the design of the ejector. Because ejector refrigerators are non-CFC based, they contribute to the reduction of hazardous effluents by avoiding them at the source. This project is jointly funded by NSF and EPA under the Partnership for Environmental Research Program.

摘要 将研究压力交换喷射器中复杂的非定常流动过程和诱导机制。 建议的工作的目标是建立性能特性和设计信息，将允许该技术用于喷射器制冷系统。 该研究将有一个实验阶段，以确定最佳设计的转子，扩压器，和喷嘴的喷射器。 理论和计算分析也将进行研究喷射器内的流动行为。 理论研究的结果将用于指导喷射器的设计。 由于喷射式制冷机不使用氟氯化碳，因此有助于从源头上避免有害排放物的产生，从而减少有害排放物的产生。该项目由NSF和EPA在环境研究计划伙伴关系下共同资助。
