Applied Physics and Mathematics Annotation << Back EXACT SOLUTIONS OF A SYSTEM OF VISCOUS GAS EQUATIONS I.A. KALIEV, G.S. SABITOVA The article presents some exact solutions of the system of viscous gas equations. Two-dimensional stationary isothermal radial gas flow and two-dimensional stationary isothermal solid-state gas rotation are described. One class of solutions to the one-dimensional problem of gas flow into a vacuum is identified. Keywords: heat-conducting polytropic gas, isothermal radial gas flow, the solid rotation of the gas, the gas outflow into a vacuum. DOI: 10.25791/pfim.05.2020.1176 Pp. 24-26.
