Lagrangian analysis of alignment dynamics for isentropic compressible magnetohydrodynamics

Abstract

After a review of the isentropic compressible magnetohydrodynamics (ICMHD) equations, a quaternionic framework for studying the alignment dynamics of a general fluid flow is explained and applied to the ICMHD equations.
