                  摘 要 ：  为 研 究 进 口 压 力 扰 动 对 旋 转 爆 轰 波 （ rotating detonation wave， RDW） 传 播 特 性 的 影 响 ， 基 于  OpenFOAM
               平台，采用二维欧拉方程，在进口处施加高频小幅（5 kHz/0.1 MPa）压力扰动，对不同当量比条件下的旋转爆轰特性进
               行了数值研究。结果表明，不同当量比下的               RDW  波数及传播模态对进口压力扰动具有显著响应，其变化主要受双波
               对撞过程及爆轰波前反应物填充特性的共同影响。燃烧室通过自适应调整平衡了能量释放和                                 RDW  稳定传播，使系统
               最终稳定在不同波数的非线性动态平衡状态。在压力扰动作用下，燃烧室内                           RDW  各项特征和参数随扰动频率发生周
               期性响应，其中     RDW  结构对扰动更敏感。当量比及          RDW  传播模态则共同决定了燃烧释热水平及出口推力，其中比冲
               主要受当量比控制，与       RDW  波数变化的相关性较弱。总体而言，高频小幅进口压力扰动主要影响旋转爆轰波的波动

               Abstract:  To investigate the effects of inlet pressure perturbations on the propagation characteristics of rotating detonation
               waves  (RDWs),  numerical  simulations  were  conducted  using  the  OpenFOAM  platform  and  the  two-dimensional  Euler
               equations  coupled  with  detailed  chemical  kinetics.  A  two-dimensional  unfolded  rotating  detonation  combustor  model  was
               established to represent the annular chamber. Periodic boundary conditions were applied in the circumferential direction, and
               non-reflecting boundary conditions were imposed at the outlet. Discretized premixed injection units were specified at the inlet
               to simulate the reactant supply process. High-frequency, small-amplitude pressure perturbations with a frequency of 5 kHz and
               an amplitude of 0.1 MPa were superimposed on the inlet total pressure with a mean value of 1 MPa, while the inlet total
               temperature was fixed at 300 K. Hydrogen–air mixtures with equivalence ratios ranging from 0.6 to 1.6 were considered to
               examine the influence of reactant composition on RDW behavior under perturbed inlet conditions. The governing equations
               were solved using a density-based compressible reacting-flow solver with a finite-volume discretization scheme. Convective
               fluxes were calculated using the KNP central-upwind scheme with a van Leer limiter, and time integration was performed
               using  a  second-order  Crank-Nicolson  method.  A  detailed  hydrogen–air  chemical  reaction  mechanism  consisting  of  27
               elementary  reactions  was  employed  to  capture  detonation  dynamics.  The  results  indicate  that  the  RDW  wavenumber  and
