Collision of nonlinear waves in logotropic system with a Coulomb-type friction
In this article, we consider the logotropic system of gasdynamics with a Coulomb-type friction to explore all possible collisions of elementary waves. We discuss the elementary waves and their properties in the phase plane to describe the exact Riemann solution. Further, we analyze all possible cases of the elementary wave interactions between same and different families of waves in the phase plane employing the solution of the Riemann problem.
