| 中文摘要: |
| 质子交换膜燃料电池（PEMFC）引射器设计通常需经过结构参数计算、计算域建模、网格划分和数值模拟等步骤，并经过多轮迭代得到一个性能较优的设计方案，所需时间成本较高。针对PEMFC引射器，通过Python编程语言将以上功能进行集成，自动计算引射器结构参数，并调用OpenFOAM软件中的blockMesh工具进行计算域建模、网格划分，以及rhoSimpleFoam求解器进行数值仿真验证，形成一套参数化的自动仿真设计工具。研究表明，该工具可显著提高PEMFC引射器设计开发的速度，从而促进汽车工业的发展。 |

| The design of proton exchange membrane fuel cell (PEMFC) ejector usually follows preliminary calculation of structural parameters, geometric modeling, meshing and numerical simulation. The time-consuming multiple iterations process is required for obtaining an optimized design of ejector. They can be integrated through Python programming with automatic calculation of structural parameters of ejector, modeling and meshing using blockMesh tool in OpenFOAM, and numerical simulation verification using rhoSimpleFoam as the solver. The development of such a parameterized automatic numerical simulation tool can significantly improve the design and development efficiency of PEMFC ejectors and promote the development of automotive industry. |
