[24] studied the effect of recess length on the mixing and combustion dynamics in a combustor with 19 bi-swirl injectors over a pressure range of 4.2-5.4 MPa. For each injector, liquid oxygen (LOX) and kerosene were injected tangentially into the center tube and coaxial outer annulus, respectively.
WebJul 8, 2024 · Granular material in a swirled container exhibits a curious transition as the number of particles is increased: At low densities, the particle cluster rotates in the same direction as the swirling motion of the container, while at high densities it rotates in the opposite direction.
