摘要:
采用二维轴对称雷诺平均方程和Spalart-Allmaras湍流模型，研究了不同混合室结构对零二次流环型超声速引射器的流场结构、盲腔真空度和引射器出口总压力等性能的影响，较好地模拟了引射器内由激波、边界层干扰诱导的复杂流场特性。结果表明，在收敛混合室前端增加适当长度的平直段可大大提高零二次流环型超声速引射器的性能。
Abstract:
The influences of different mixing chamber structures on flowfield structure, vacuum in blind-cavity and total pressure at ejector outlet of the Zero-second-flow annular supersonic ejector is investigated by using two-dimensional axisymmetric Navier-Stokes equations and Spalart-Allmaras turbulent model . The characteristics of complex flowfield induced by both shock waves and the boundary layer are commendably simulated. The results show that the performance of Zero-second-flow annular supersonic ejector is remarkably promoted when a tube is added at frontend of the convergent mixing chamber.
