Dimensionless parameters (plasmapy.formulary.dimensionless)

Module of dimensionless plasma parameters.

These are especially important for determining what regime a plasma is in. (e.g., turbulent, quantum, collisional, etc.).

For example, plasmas at high (much larger than 1) Reynolds numbers are highly turbulent, while turbulence is negligible at low Reynolds numbers.

Functions

beta(T, n, B)	The ratio of thermal pressure to magnetic pressure.
quantum_theta(T, n_e)	Compares Fermi energy to thermal kinetic energy to check if quantum effects are important.
Reynolds_number(rho, U, L, mu)	The Reynolds Number is a dimensionless quantity that is used to predict flow patterns in fluids.
Mag_Reynolds(U, L, sigma)	The Magnetic Reynolds number is a dimensionless quantity that estimates the relative contributions of advection and induction to magnetic diffusion in a conducting medium.
