1D Euler Boundary Conditions using Riemann Variables??Hello all,
I am at the moment writing a code for a uni project using a second order Lax-Wendroff scheme to model unsteady flow. I am trying to implement boundary conditions using characteristics but am struggling....the method described by Benson for a 'closed' boundary does not produce reflections but results in big oscillations in my program: 1) Do I not need to set the temperature at the boundary to be a constant? 2) Will the homoentropic method at the boundary suffice? I would really appreciate any help :confused: Thanks, Ozzy |
