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 cy...

description 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 numerical simulation has been used on the basis of the gas dynamics equations by the CIP-CUP method on the dynamically adaptive Soroban-grids without explicit tracking of the interphase boundary. It has been found that three regimes of impact are set in the examined range of the angles. At the small angles the impact with shock wave attached to the wall without liquid spreading is realized. An abrupt transition to the regime with the shock wave detached from the wall together with the radial jet of the liquid spreading on the wall takes place with increasing the angle. A smooth transition to the shockless regime with the radial liquid jet is realized with further increasing the angle.
