Abstract : The scale of turbulence is a quantity which has the dimension length and which is associated with the size of an eddy. It may be thought of as the average size of eddies. An eddy must be considered as any disturbance of the smooth flow. The description of turbulence in terms of intensity and scale resembles the description of the molecular motion of gas by temperature and free path.
