Background/Objectives: The purpose of this study is to investigate the reduction and recycling of sent gases to the flare by ejector. Methods/Statistical analysis: A balance and integrated model of CFD is provided so that the validity of this study suits for ultrasonic ejector. We investigatedthe phenomenon and behaviors of the ejector accurately with details. The symmetrical geometry of ejector was selected to achieve simplicity and greater accuracy in the calculations. Accuracy of calculation is the convergence of solution by fluent software. Findings: The practical ejectors work under a variety of boundary and initial operating regimes. In mentioned condition, there is the possibility of its replacement with the compressor in a flare gases recovering system. The efficiency of CFD was obviously clear in calculations of various ideal gases. Moreover, it is possible to design an algorithm by mathematical tools in order to minimize the computational efforts and time. This work also leads to reduction of modeling time of actual gas with minimum loss of function.Applications/ Improvements: The convergence of calculations indicates the significance of results and their consistence with theories and ejector operation.
