Studying the process of pulsed loading of a water-filled cylindrical container
The paper solves the problem of determining the pressure field in a liquid during experimental testing of the motion of objects under water. A calculation method is given for determining the pressure field on the walls of a cylindrical container during the intensive development of a spherical gas cavity in a liquid. The presence of solid container walls is taken into account by placing fictitious sources on them with an intensity that ensures the fulfillment of the non-leakage condition. The law of development of a gas bubble, similar to the Rayleigh equation, is derived; the mass of gas in the bubble is determined in accordance with the Saint-Venant equation. The pressure at the container point of interest to the researcher is calculated with the use of the Cauchy-Lagrange integral. The constructed method makes it possible to estimate the loads on the experimental stand in the event of an emergency situation.
