- 摘要:
- 针对采用多目标优化方法设计的超声速燃烧冲压发动机非对称喷管,采用RNG k-ε湍流模型和有限体积方法数值求解有组分的守恒形式Navier-Stokes方程,数值模拟喷管不同入口马赫数条件下的喷管流场和性能。计算结果表明:喷管入口马赫数的变化会对喷管内流参数带来一定影响,导致喷管的推力和升力同时增大或减小,飞行器的配平性能可能会受到一定影响。
- Abstract:
- The RNG k-ε turbulence models and finite volume method were used to solve the conservative Reynolds-averaged Navier-Stokes equations and simulate the flow field and performance of the scramjet asymmetric ramp-nozzle designed with multi-target optimization method. The characteristics of the nozzle were numerically studied under the condition of various nozzle inlet Mach number. The simulation result shows that the variation of the nozzle inlet Mach number may influence the internal flow parameter of the nozzle, the increased or reduced inlet Mach number leads to up or down in thrust and lift force simultaneously, and maybe affects the stabilization of hypersonic air vehicle.
