Numerical schemes for quasi-1D steady nozzle flows

作者:

Highlights:

• Describe numerical schemes for unsteady 1D flow in ducts of variable cross-section.

• The numerical techniques are capable to preserve steady states at the discrete level.

• The convergence and robustness of the methods are confirmed by the numerical test.
