| description | It is of great significance to investigate the mechanism of the propeller slipstream influence on the aerodynamic performance of the submerged inlet to keep the stability of the engine. A systematical numerical computational fluid dynamics (CFD) method is established to simulate the slipstream and inner flow of oil radiator for a certain turboprop aircraft. The simulation analysis is performed for the aerodynamic characteristic of the submerged inlet of the oil radiator within the propeller slipstream. Moreover, four vortex generators are designed to control the flow around inlet of the oil radiator to increase the flow rate affected by the inhaled low energy flow of the boundary layer in the inlet. The results show that: within the influence of the propeller slipstream, the flow in the submerged inlet is deviated and can hardly generate stable vortex. However, the reasonable vortex generator can effectively improve the flow of the submerged inlet by increasing the flow rate with 12%. |
