- Аннотация: http://congress.imbm.bas.bg/uploads/simplex/pdfs/13NCTAM_Book_of_Abstracts.pdf Shock propagation through dusty gas takes place in wide array of problems, including such important topics as coal mine explosion safety and shock-impulse methods of powder coating. The key role is played by interaction of with local clouds of suspended particles. An interaction of a shock with cylindrical cloud of low-concentration quartz dust is studied in the present work. A model of equilibrium dust-gas mixture based on Euler’s equations is used. Refraction and focusing processes of the incident shock are described. Two qualitatively different interaction patterns – internal and internal – depending on dust concentration in the cloud are found. A dependence of peak shock focusing point and focusing intensity on dust volume concentration in range from 0.01% to 0.15% is determined. With dust concentration increase, focusing point approaches the cloud edge and shifts into the cloud, while shock focusing intensity rises nonmonotonically. The study was performed using the computational resources of the Moscow State University cluster with financial support of Russian Foundation for Basic Research (project no. 16-29-01092) and Council for Grants of the President of the Russian Federation (project NSh-8425.2016.1).
