Richardson Number

The Richardson number is the dimensionless number that expresses the ratio of the buoyancy term to the flow shear term.

The Richardson number equals the gravitational acceleration times the characteristic height divided by the characteristic speed squared.

Formula

QuantityVariable["Ri", "RichardsonNumber"] == (QuantityVariable["g", "GravitationalAcceleration"]*QuantityVariable["h", "Radius"])/QuantityVariable["u", "Speed"]^2

symbol description physical quantity
Ri Richardson number "RichardsonNumber"
g gravitational acceleration "GravitationalAcceleration"
