The authors develop a cylindrical Smoothed Particle Hydrodynamics (SPH) formulation of Riemann problems with an explicit formulation for the artificial viscosity adapted to solve Euler equations. Numerical results are compared to exact solutions and observations are made on numerical parameters influence.
