摘要

Previous investigations on the submerged inlets show that the counter-rotating vortex pair originated from the side edge is helpful to inhale the external flow into the duct but increases the mixing loss of the inlet. To improve the performance of this type of inlet, a flow control method based on bleeding vortex is brought forward in this paper which is expected to utilize the positive effect of the vortex pair and to reduce the accompanied disadvantages. Computational results indicate that the control method is effective with the total pressure recovery coefficient increased by 2.8% and the distortion index decreased by 51.0% at the design condition as compared with the baseline case. Furthermore, the corresponding experimental results have proved the effectiveness of the control technique.
