An experimental combustor, designated BKH, is operated at DLR Lampoldshausen to investigate high-frequency combustion instability phenomena. The combustor operates with liquid oxygen (LOx) and gaseous or liquid hydrogen propellants at …
In BKH, Webster et al. [10] showed that a nonlinear coupling was observed between measured dynamic pressure and §ame response visualized with both visible and OH* chemiluminescence imaging. Areas of high combustion rate and density gradients can be detected by OH* emission and visible imaging, respectively.
