Vasilyev A.P., Pavlov A.S. SHOCK PRESSURE INCREASE AT COMPRESSION ISOTHERMAL STEAM BUBBLE IN A VISCOUS LIQUID. The article deals with the dynamics of a compression bubble in a viscous isothermal liquid under the influence of superficial tension forces, as well as pressure, inertia and viscous friction. The settlement parities for shock increase of pressure in a liquid are received, from which follows, that at the initial moment of time at the front shock waves the pressure more than 3000 atm is reached. The equations of dynamics of a viscous liquid were integrated numerically by method Runge-Kutta. The comparison of calculation with the classical formula Raley for time compression of a spherical cavity in an ideal liquid is given.
