unsteady 1-D euler equations in a nozzle
I am a university student. I must solve an unsteady 1-D problem for a nozzle flow using euler equation with MATLAB. This is a PDE initial boundary value problem. I'm using a finite volume method QUICK and a fourth order RUNGE-KUTTA (the first one for the space derivatives, the second one for the time derivatives). The solution tends towards instability even if I use a very small time step and consequently a small CFL number. I would like to thanks all the people would give me information about this problem.
