Influence on the mixed flow-field performance by the flow rate of He in the secondary flow

The circumstance of primary flow mixed with the secondary flow are numerically simulated by varying the flow rate of He in the secondary flow with the same primary flow and the same flow rate of I2 in the secondary flow. The conclusion is obtained by comparing and analyzing these results, that the penetration depth of the transverse secondary flow in the primary flow extends and the state of primary flow mixed with the secondary flow becomes better with the flow rate of He in the secondary flow increased, until the primary flow and the secondary flow are welldistributed.
