Using Differential Forms to Find Symmetries in the Noh Problem for an Ideal Gas in a Spherical System
- Los Alamos National Lab. (LANL), Los Alamos, NM (United States)
The Euler equations describe inviscid, compressible gas flow and are derived using the laws of conservation of mass, momentum, and energy. From these equations a common test problem, the Noh problem, can be solved for invariant solutions in planar, cylindrical, and spherical geometries. Using Lie group analysis methods, we will solve the Noh Problem for an ideal gas in a spherical system.
