Some developments in the application of renormalisation methods to turbulence theory
Abstract
The use of renormalization methods in turbulence theory is discussed. A renormalization theory (McComb, 1978) is used to calculate the statistical parameters of freely-decaying isotropic turbulence. Some preliminary results show that the theoretical spectra are in good agreement with experimental results. Preliminary results are also presented for the isotropic part of the effective viscosity calculated by a new technique of iterative averaging (McComb, 1982).
