A variant of the inverse method of characteristics is presented, in the algorithm of which an additional fractional time step is introduced, which makes it possible to carry out calculations with a large time step without loss of accuracy and stability. Calculation formulas of the modified inverse method of characteristics are given for a single-velocity generalized equilibrium model of a gas–liquid mixture. When calculating multidimensional problems, the original system of equations is split into a number of one-dimensional subsystems, for the calculation of which a modified inverse method of characteristics is applied. Using the proposed method, the spreading of a liquid column under the influence of gravitational forces for flat and axisymmetric cases, as well as a drop of liquid falling into a hard smooth barrier were calculated. The calculation results are compared with the available experimental data. [ABSTRACT FROM AUTHOR] |
