涡流比
[动力] swirl rate
- 用三维数值模拟的方法研究了不同涡流比下直喷式柴油机缸内湍流流动的规律。
The turbulent flow characteristics in cylinders of direct injection diesel engine under different air swirl ratios are analyzed by multi dimensional simulation methods. - 在此基础上对涡流比和喷油压力进行了综合优化匹配模拟，为小缸径柴油机燃烧系统的设计提供了理论依据。
Finally, the matching of swirl ratio and spray pressure is simulated, which offers the theoretical foundation for the design of combustion system of small-bore diesel engines. - 该方法可适于任意形状的燃烧室，能反映出喷油压力、喷油嘴结构及安装位置、进气涡流比等参数与燃烧室形状的匹配关系。
The method can be used for combustion chambers with any shape to match the fuel injection pressure, nozzle construction, injector position and intake swirl ratio with chamber shape.
