Representation of the plasma fluid equations in Miller equilibrium analytical flux surface geometry

The plasma fluid equations are represented explicitly in the magnetic flux surface coordinate system resulting from the analytical Miller equilibrium solution of the Grad-Shafranov equation. The magnetic geometry is characterized by the elongation, triangularity, and location of the displaced major radius of the flux surface. The resulting fluid equations can be solved directly without the necessity of first solving the Grad-Shafranov equation numerically to define the flux surface coordinates.
