The characteristics of asymmetric impinging streams were measured with hot wire anemometry and simulated with CFD. The results of numerical simulation were consistent with the results of experiments. The characteristics of axial velocity of asymmetric impinge streams were similar with those of free round jet except in the vicinity of the impinging face. When the distance of two nozzles was fixed

the offset of impinging stagnation point on the axis increased with the ratio of velocity and the nozzle diameter. When the ratio of velocity was fixed

the offset of impinging stagnation point on the axis increased with the distance of two nozzles.
