Effect of air cooled spraybar heat insulation sleeve height on performance of mixer and diffuser

  • 摘要: 针对一种带气冷喷油杆的混合扩压器,基于Navier-Stokes方程组建立了流场三维数值计算模型,研究了气冷喷油杆的隔热套高度对一体化混合扩压器流场、流阻特性和混合特性的气动热力性能影响规律。结果表明:隔热套高度对混合扩压器热混合效率影响不大,总体变化范围小于0.008;随着隔热套高度的增加,静压恢复系数逐渐减小,流阻系数和压力损失系数逐渐增大;在混合扩压器出口截面处,总压恢复系数随隔热套高度增加而逐渐减小,且总体变化范围较小,由0.991 1减小到0.990 7。
