摘要:
为了研究带收敛喷管的脉冲爆轰发动机PDE(Pulse Detonation Engine)的推力性能,建立了一维欧拉方程,应用CE/SE方法数值求解.计算分析发现,收敛喷管对脉冲爆轰发动机的内流场产生了重要影响;当喷管收敛角度小于8°时,带收敛喷管的脉冲爆轰发动机的冲量和平均推力比不带喷管时大;带小收敛角度喷管的PDE,其平均推力随喷管长度增加而增大;带大收敛角度的PDE的平均推力随喷管长度增加先增大后减小.研究结果对PDE喷管的设计具有理论指导和参考作用.
Abstract:
To eva luate the propu lsive perform ance o f Pu lse Detonation Eng ine( PDE) w ith d ifferen t convergent nozzles, the Eu la r equation is bu ilt and so lved w ith CE /SE m ethod. The resu lts o f num erical sim ulation of series of nozzles ind-i ca te that the converg ent nozzles have an sign ificant effect on the interna l flow field o f PDE, and that com pa red w ith PDE w ithout nozzle, the one w ith converg ent nozzle in a ang le less than 8bprov ides h igher im pu lse and ave rage thrust. For a sm a ller ang le conv ergent no zzle, the increas ing leng th o f nozzle leads to an augm enta tion on the av erage thrust of PDE, wh ile fo r a larg er one, the averag e thrust increases first and then reduces w ith the increas ing leng th. Therefore, a ll resu lts here prov ide som e helpful theo ry gu ide and re ference for the nozzle design of PDE.
