![]() ![]() primary flow (active gas) through nozzle: The HP (active) gas is accelerated to sonic velocity in the throat of the ejector inlet nozzle.The applicable equations are provided by Huang et al as follows: Findings are presented herein, together with a recommended simplified method for the prediction of ejector performance.įigure 1 shows a sketch of gas/gas ejector based on. Results were analyzed and compared with published results and with the simulation results obtained by using cfd codes (as UNISIM and HYSIS). A study was performed to establish a simpler methodology for ejector design and for the prediction of performance, based on the following: Ī thermodynamic spreadsheet model was prepared based on equations. Gas ejector design can however be determined by rigorous calculation using the applicable equations. Xperience during the execution of engineering design and consultancy services has shown that the commonly available process simulation software is not applicable for many gas/gas ejector applications encountered. From this, a methodology was established to determine ejector performance at a conceptual level, using commercial cfd simulation software Pierre van Eeden and Dario Ercolani ILF Consulting Engineers (ILF Beratende Ingenieure GmbH)Į Fig. ![]() A Method for Prediction of Gas/Gas Ejector Performance A correlation for ejector efficiency with accuracy range ☒% was found between the model and published results. ![]()
