Measurement and Modeling of Anisotropic Turbulent Flows
Turbulence subjected to the mean strain field of a contraction, and the relaxation from the highly anisotropic states downstream contractions was studied. The pressure-strain correlations, which are responsible for the intercomponent energy transfer were estimated from other turbulence statistics. High accuracy in the determination of these was ensured by use of an angle calibration technique for the hot-wires. The degree of anisotropy of the dissipation rate tensor was found to be an important factor when comparing the data with various standard models for the pressure-strain terms.
