Abstract
The effects of lateral injection rate on the inlet mainstream that deflects the reattachment point upstream were investigated with special focus on the intimately relation between the maximal reverse rate and the entrainment fluid. The analysis revealed that the enhancement of blowing rate suppresses apparently the strongest reversal strength because of the enlargement of the corner eddy and the lift of the main recirculating bubble from the porous wall. For the case without injection, about 15.63% of the new shear layer was deflected upstream the reattachment point, whereas approximately 12.5 and 7.5% of the new shear layer were deflected upstream for the flow fields B and C.
