Abstract:

Water jets are produced by vertically accelerating a rotating cone partially filled with water. It is shown that the acceleration of the parabolic meniscus results in a motion similar to that observed in a shaped explosive charge. Monroe jet. Acceleration of the cone is effected by means of an inductive electromagnetic accelerating device conical pinch whose theory is developed in terms of the WKB approximation. A second order inviscid theory is presented of the motion of the fluid in the cone in terms of the Penney-Price linearization procedure and it is shown that good agreement for the jet head velocity can be achieved for low velocities.
