Extremal Properties of Pressure in Axisymmetric Vortex Gas Flows
Extremal Properties of Pressure in Axisymmetric Vortex Gas Flows is a scholarly work, published in 2018 in ''TsAGI Science Journal''. The main subjects of the publication include classical mechanics, shock wave, ideal gas, stagnation pressure, computational fluid dynamics, stagnation temperature, turbulence, physics, Euler equations, Euler's formula, choked flow, transonic, stagnation point, vortex, supersonic speed, boundary value problem, shock, flow, rotational symmetry, Kinetic theory, mechanics, and mathematics. Based on the exact Euler equations of steady axisymmetric nonswirling vortex ideal gas flows, it is shown that the pressure minimum value is reached at the boundary of the subsonic flow domain in the absence of internal stagnation points.
