基于射流冲击作用的舰机适配性数值分析与优化

摘要/Abstract

摘要： 准确分析和控制射流冲击对航母甲板环境的影响是新型喷气偏流板设计和布局的关键所在。为了确定射流冲击影响最小的偏流板布局，运用有限体积法，采用分区混合网格方案，结合雷诺时均纳维斯托克斯（RANS）方程和SST k-ω湍流模型对喷气偏流板在不同布局下的射流冲击效应进行三维数值模拟。选取舰载机双发动机全加力状态时喷气偏流板与发动机距离不同、喷气偏流板倾角不同共12种布局组合进行射流冲击效应的对比计算,计算结果显示了喷气偏流板各布局下的流场参数、传热特性、尾喷口温升、冲击力和力矩等分布规律。定性和定量分析了燃气射流冲击下温度场和速度场的危险区域，结果表明，偏流板与发动机距离5 m、偏流板倾角45°时的布局更有利于将燃气射流向上引导。在此基础上，基于倾角最小化原则及二次导流原理优化设计了一种导流隔热性能好、工作稳定性高的被动隔热式喷气偏流板装置。

Abstract: Accurate analysis and control of the jet impingements on flight decks was a key factor for the design and layout of a new jet blast deflector.In order to determine the reasonable layout with minimal impacts of gas jets on the surrounding environment of flight decks, finite volume method was used to simulate numerically impact effects of the twin-engine gas jet on a jet blast deflector in different layouts by using Reynolds-averaged Navier-Stokes(RANS) equations and shear-stress transport(SST) k-ω model based on sub-domain hybrid mesh.Twelve layouts consisting of different distances for the jet blast deflector and engine and different inclination angles of the jet blast deflector were selected for computing and comparing the jet impact effects when the twin engines for air vehicle are in full afterburning state.The computational results show distribution and regularities of flow field parameters, heat transfer characteristics, temperature rise of tail nozzle, impact force and moment in different layouts of the jet blast deflector.The dangerous areas of temperature field and velocity field in the impact processes were analyzed qualitatively and quantitatively.The results show that the layout in deflector and engine distance of 5 m and deflector inclination angle of 45° is more conducive to guide the gas jet upwards.Furthermore, a passive heat-insulated jet blast deflector device with good diversion performance, good thermal conductivity and high working stability was designed based on the principle of minimum inclination angle and secondary diversion.

Key words: jet blast deflector, jet impingement, carrier/air vehicle integration, numerical analysis, optimal design
