Expression, Corrsin

The scalar length scale, Ls, is assumed to be equal to in the above expression. For systems with low values of Schmidt number, Corrsin s model reduces to that of Spalding, albeit with higher coefficient (0.5). Corrsin s model is found to be useful... 

This experimental result rules out einy explemation based on a reaction/diffusion mechsmism, in which the diffusion time tjj varies as given by the classical expression of CORRSIN (13). ... 

In effect, if we assume that the energy input e is due to the kinetic energy of jets which varies roughly as t 3, CORRSIN S expression leads to an increase of t with t. An alternative ex-pleuiation is proposed below. 

Corrsin s (1957, 1964) theory considers the time scale, t, required for the decay of the concentration fluctuations. This can be expressed in terms of the intensity of segregation ...
