A novel model for ejector performance mapping across the full operating range

The global rise in temperature raises non-negligible concerns regarding the performance of absorption-based cycles. Recently, multiple studies have shown the ability to mitigate harsh temperature conditions through the use of an ejector. The ejector enables an increase in pressure in certain components, such as the condenser or the absorber, in order to facilitate heat rejection. For this reason, an ejector has been designed and fabricated. The next step is to develop a proper numerical model to investigate the cycle incorporating the ejector. In the literature, state-of-the-art simplified models fail to properly assess the designed ejector, as its operating conditions deviate significantly from typical ones. Thus, a novel modeling approach must be introduced. The current work therefore consists of, first, defining a novel approach to quantifying the performance of such an ejector, and second, developing a model that is able to reproduce its performance curve as a function of the desired operating conditions.
