Proceedings of IBRAE RAS, Issue 16:  Models and methods for calculation of multidimensional two-phase flows in the presence of surface tension forcesProceedings of IBRAE RAS, Issue 16: Models and methods for calculation of multidimensional two-phase flows in the presence of surface tension forces

Ed. by L. A. Bolshov

An overview of current status numerical modeling of compressible multiphase flows for nuclear industry applications is reviewed. Also numerical methodology for modeling of complex shock-wave processes in two-phase media in the presence of surface tension forces is presented. The methodology allows to model phenomena of boiling, evaporation and condensation by means of the method of discrete equations using the HLLC solver for aligning the temperature and Gibbs, taking into account peculiarities two-phase problems. The method is implemented in the form of a three-dimensional parallel code that can be used for calculations on clusters, for example “Lomonosov” (Moscow State University, Moscow). The features of the developed technique and its advantages in a comparison with others are discussed. Examples of its application to solve specific problems are demonstrated.
For students, postgraduates and specialists in the field of numerical methods for solving differential equations of mathematical physics.

Ed. by L. A. Bolshov

The two-phase compressible flows numerical models equipped with Godunov method, using the precise or approximate Riemann solvers, are considered for calculations of shock-wave processes in twophase mixtures.

The method to improve the robustness of numerical algorithm for mechanical equilibrium two-phase model, using pressure non equilibrium model with relaxation, is explained. Two different numerical approaches to simulate evaporation and condensation phenomena underneath from process intensity and velocity, using reactive Riemann solver or special relaxation procedure for temperatures and chemical potentials of two-phase mixture components, are discussed.

The issue is intended for students, post-graduate students and specialists in numerical methods for
solving differential equations of mathematical physics.
