Chandrasekhar Number

The Chandrasekhar number is a dimensionless quantity used in magnetic convection to represent the ratio of the Lorentz force to the viscosity.

The Chandrasekhar number equals the product of the square of the magnetic flux density, the square of the characteristic length and electric conductivity divided by the kinematic viscosity and mass density.

Formula

QuantityVariable["Q", "ChandrasekharNumber"] == (QuantityVariable["B", "MagneticFluxDensity"]^2*QuantityVariable["l", "Length"]^2*QuantityVariable["σ", "ElectricConductivity"])/(QuantityVariable["ν", "KinematicViscosity"]*QuantityVariable["ρ", "MassDensity"])
