High Resolution Nonoscillatory Central Difference Schemes for the 2D Euler Equations via Artificial Compression
We suggest to augment second-order, nonoscillatory, central difference schemes with Harten’s artificial compression method (ACM) to sharpen the resolution of linear fields. ACM employs a partial characteristic decomposition to single out the linear fields, for which a steeper reconstruction is applied. The remarkable power of this technique is demonstrated for three test problems for the Euler equations from gas dynamics, and its dangers are pointed out.
