Godunov-type schemes for the pressureless gas dynamics and related models
作者:
Highlights:
• New Godunov-type schemes for weakly hyperbolic pressureless gas dynamics systems are developed.
• Resulting schemes outclass previously developed FDS based Roe-type works.
• Several computational examples are considered to demonstrate the accuracy and robustness of the developed schemes.
