The changes in the mean velocity and turbulent flow fields of the plane wall jet disturbed by a circular cylinder which is placed at various distances from the plane wall and the fluid dynamical forces acting on the cylinder are investigated experimentally. The results show that the mean and fluctuating velocity profiles are conciderably affected by the disturbance of the cylinder, and that the change in the profiles of the mean flow and turbulent field exhibits different behaviour according to the locations of the inserted cylinder. The drag coefficient of the cylinder has the maximum value at the location of y_c/d=1.2,whereas the lift coefficient has the minimum one.
