The comparison of a new theory of gridproduced turbulence with an experiment
Abstract
Nakagawa (1979) has solved the problem of gridproduced turbulence as an initial value problem. The turbulent energy decay law has been derived under the assumption that the turbulence behind the grid is isotropic and the pressurevelocity correlations are negligibly small. In the present investigation, the theory derived by Nakagawa in the earlier study is compared with an experiment conducted by Batchelor and Townsend (1948). It is found that the theory is applicable within a certain region for which the value of the distance from the grid lies in a certain range.
