Title |
Solitary wave interactions at large Mach numbers |
Abstract |
Numerical experiments on the ion acoustic plasma equations show the Korteweg deVries equation to be an extremely robust model: the qualitative features of the two soliton interaction are preserved even at large Mach numbers, where the KdV approximation is no longer quantitatively accurate. Collisions remain almost perfectly elastic, while the scattering shifts are larger than those in the KdV two soliton solution. |
