Leonov A.A., Chudanov V.V. 

The model of two-phase medium is considered in view of micro-inertia. The basic equations are received by a variation method based on use of a principle of a least action of Hamilton. The numerical modeling is executed with use of a modified method of piecewise parabolic approximation (PPM). The results of test calculations for behavior problem of gas bubbles in a tube with a fluid and for distribution problem of a shock wave in fluid medium with gas bubbles are presented.
