By the early 1940s, after several of the canonical shear flows had been mea- sured and documented in terms of mean velocity and Reynolds stresses, at- tention began to turn to the distribution of scalar fields.
Examples of scalar fields include the temperature or the concentration associated with species being transported by turbulence.
7.4 Structure of scalar fields in isotropic turbulence
He went on to define integral and Taylor micro-scales appropriate for the scalar field, namely
Following Kolmogorov's (1941) important theory of local isotropy and sim- ilarity hypotheses regarding turbulent velocity fine-structure, and in fact his own along with Obukhov's (1948) theory for fine-scale scalar fields (Corrsin, 1951b), Corrsin became interested in the intermittent behavior and the ge- ometric properties of fine-scale turbulence.
