Prandtl Number Using Thermal Diffusivity

The Prandtl number is a dimensionless number defined as the ratio of momentum diffusivity to thermal diffusivity.

The Prandtl number equals the kinematic viscosity divided by the thermal diffusivity.

Formula

QuantityVariable["Pr", "PrandtlNumberHeatTransfer"] == QuantityVariable["ν", "KinematicViscosity"]/QuantityVariable["α", "ThermalDiffusivity"]

symbol description physical quantity
Pr Prandtl number for heat transfer "PrandtlNumberHeatTransfer"
α thermal diffusivity "ThermalDiffusivity"
