Aimed at studying the influence of different defectors on impact properties of parallel LOX/kerosene engine exhaust plume, flow fields of double-nozzle and six-nozzle LOX/kerosene engine exhaust plume impacting on three diversion troughs of without deflector, with a wedge deflector, with a conical deflector were calculated with the CFD software, and influences of different deflectors on impact properties were compared and analyzed. It is found that, after double-nozzle LOX/kerosene engine exhaust plume vertically impacting on the diversion trough without deflector, plume which flows along the side surface of the diversion through and plume reflected upward would bring high temperature effect on the environment directly above the diversion trough., while The wedge deflector and the conical deflector could avoid the high temperature effect of plume on the environment directly above the diversion trough. It is showed that the effects of flow-guiding and cooling of cone-shaped diversion device is better compared with wedge-shaped diversion device.
