| description | Aiming at the application of the ejector in the fuel cell engine for vehicles, by fitting the experimental data of anode pressure drop of 40kwlevel proton exchange membrane fuel cell (PEMFC), the relationship expression between anode pressure drop and current was obtained The threedimensional ejector numerical model of anode hydrogen circulation system was established by the computational fluid dynamics (CFD) method, whose accuracy is verified by the experimental data Finally, the fitted anode pressure drop expression is applied to the simulation optimization of the model The performance of the ejector under the whole operating range of the target system was measured, and the optimum values of main sizes is determined, including nozzle throat diameter, mixing chamber diameter, mixing chamber length, and the nozzle position relative to the mixing section The simulation results show that, compared with the constant pressure drop model, the ejector model established in this paper can more accurately evaluate the operating performance of the ejector under the entire operating conditions, and at the same time, the optimized ejector under the studied operating conditions can maintain the hydrogen recirculation ratio above 12 |
