A disturbance produces by a jet impinging on an object. The turbulence is useful for the mixing. The mean and r.m.s. values of concentration and velocity were measured in the wall jet regions of impinging jets by the hot-wire techniques. The wall jets were formed by impinging respectively helium; air and carbon dioxide gas jets to the disk or cone with various vertical angles set up in still air. The mixing of gases is very enhanced by impinging jets in comparison with an ordinary free jet. The relation of the measured values and the vertical angle is discussed. The relationship between decays of maximum values of concentration and velocity along the main stream and the vertical angle is expressed.
