Abstract
The article studies the applicability of the Baer–Nunziato two-fluid model to the problem of interaction of a shock wave with a foam layer. The determining system of equations is formulated. A computational algorithm based on the Harten–Lax–Van Leer scheme with contact discontinuity resolution, including phase velocity and pressure relaxation stages, is proposed and described in detail. Using the proposed computational technology, the problem of propagation of a weak perturbation in a two-phase medium is considered. The propagation velocity obtained is close to the estimate using Wood formula. The problem of the interaction of a shock wave with a foam layer near an impenetrable wall is also considered. The formulation corresponds to full-scale experiments. The nonstationary wave dynamics realized in this problem using the proposed model is described. Good qualitative and quantitative agreement is obtained between the calculation results and experimental data.
期刊介绍：
High Temperature is an international peer reviewed journal that publishes original papers and reviews written by theoretical and experimental researchers. The journal deals with properties and processes in low-temperature plasma; thermophysical properties of substances including pure materials, mixtures and alloys; the properties in the vicinity of the critical point, equations of state; phase equilibrium; heat and mass transfer phenomena, in particular, by forced and free convections; processes of boiling and condensation, radiation, and complex heat transfer; experimental methods and apparatuses; high-temperature facilities for power engineering applications, etc. The journal reflects the current trends in thermophysical research. It presents the results of present-day experimental and theoretical studies in the processes of complex heat transfer, thermal, gas dynamic processes, and processes of heat and mass transfer, as well as the latest advances in the theoretical description of the properties of high-temperature media.
