Development of Control Model for Critical Operation Ejector

摘要：

Existing ejector models are either very complex nonlinear ones with coupled equations or empirical correlations suitable for particular ejector geometries and operation conditions, resulting in difficulties for real time applications. Therefore, it is practically important to develop a simple, yet accurate ejector engineering model that will yield better real time control and optimization of ejector refrigeration systems (ERS). In this paper, a new, simple, yet accurate hybrid ejector model is presented, which is induced by shock circle model 1 based on fluid dynamics and energy balance principles. Comparison with the published experimental data shows that the model is robust and gives a better match to real performances of all the 11 different ejectors over the entire operating range when compared to existing models in the literature.
