Richardson Number


The Richardson number (Ri) is named after Lewis Fry Richardson (1881 – 1953). It is the dimensionless number that expresses the ratio of potential to kinetic energy. In certain fields the Froude number is more commonly used and is the reciprocal of the square root of the Richardson number or Ri = 1/Fr^2
