IMPACT OF A LIQUID CONE ON A PLAIN RIGID WALL

Impact of a Liquid Cone on a Plain Rigid Wall

A numerical study of high-speed (with the velocity of 250 m/s) impact of a liquid cone (cone-like jet) on a plain rigid wall has been performed.The range of the angles of inclination of the cone surface to the wall corresponds to that of their variation in the process of impact on the wall of a cylindrical jet with the semi-spherical end.The direct
