The radial distribution of the tangential velocity of turbulent rotational gas flow in the cylindrical vortex chamber is depended on not only the Reynolds number Rec but also the construction of this chamber. When the ratio of the body diameter D1 to the diameter Do of the tangential inlet pipe is larger than 6〜7 , so the distribution of the tangential velocity in the quasi-free vortex region is not always represented by the simple free vortex model. A cause of this effect is mainly depended on the distribution of the radial velocity. In this paper a comparison of the experimental results of the tangential velocity of gas flow in the quasi-free vortex region with the numerical calculation by Runge-Kutta method is discussed.
