Gaseous hydrogen/liquid oxygen turbulent shear coaxial flames were subjected experimentally to both pressure antinode (PAN) and pressure node (PN) transverse acoustic forcing as a function of the gas-to-liquid momentum flux ratio. The response of the flow was recorded using simultaneous high-speed imaging of backlit shadowgraphs and ${\mathrm{OH}}^{*}$ chemiluminescence emission. It was observed that a wave amplification mechanism, defined in Sec. III, previously observed for unforced flows, remained present in the forced flows but was modified by the forcing. The response tended to be axisymmetric for PAN forcing, where the pressure fluctuations are symmetric, and asymmetric for PN forcing, where the velocity fluctuations are asymmetric. Additional analyses performed included dynamic mode decomposition (DMD) and an analysis of the ${\mathrm{OH}}^{*}$ wave trajectories as a function of time. Beyond the main observation that the wave amplification mechanism remained operative not only for unforced flows but also for both kinds of transverse forcing, secondary observations included a greater relative effect on the flow for PN forcing than for PAN forcing and a reduced general response of the flow to the acoustics at higher momentum flux ratios. The velocity of waves observed in the ${\mathrm{OH}}^{*}$ emission were found to depend mainly on the shear layer velocity and not directly on the acoustics.

气态氢/液氧湍流剪切同轴火焰在实验中受到压力波腹（PAN）和压力节点（PN）横向声强迫的影响，这是气液动量通量比的函数。流动的响应是通过同时使用背光阴影图和${哦}^{*}$化学发光发射。据观察，波放大机制，在第二节中定义。以前观察到的非强迫流动的III，仍然存在于强迫流动中，但通过强迫进行了修改。对于PAN强迫，压力波动是对称的，而对于PN强迫，速度波动是不对称的。执行的其他分析包括动态模式分解（DMD）以及对${哦}^{*}$波轨迹是时间的函数。除了主要的观察结果，即波放大机制不仅对非强迫流动仍然起作用，而且对于两种横向强迫仍然起作用之外，次要观察还包括，与PAN强迫相比，PN强迫对流体的相对影响更大，并且对流动的总体响应有所降低动量通量比较高时的声音。在海浪中观测到的波速${哦}^{*}$ 发现发射主要取决于剪切层速度，而不直接取决于声学。
