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.
