基于电弧放电等离子体热阻塞机理，数值模拟等离子体产生于超燃燃烧室横向喷流上游时燃烧室流动过程，分析激励器位置与激励强度两个关键因素对等离子体作用效果的影响。结果显示：激励器开启下等离子体区域形成一高温虚拟凸起，诱导出斜激波；随着激励位置从燃烧室入口向喷流移动，喷流上游回流区 x 向尺寸呈先增后减趋势，在最优激励位置激励时，分离激波强度显著降低。

The flow field of scramjet combustor with plasma generated at the upstream of transverse jet is numerically simulated based on the thermal blocking mechanism of arc discharge plasma. The effects of the position of actuator and actuating intensity on the performance of plasma are analyzed. The results indicate that an oblique shock wave is formed by high temperature virtual hump of plasma. As the position of actuator moves towards jet, the x direction size of upstream recirculation zone increases and then decreases, under the optimized actuating position, the strength of the separation shock wave drops obviously.
