Response of homogeneous turbulence to a sudden change in the position of the principal axes of the strain tensor
Abstract
The paper studies the evolution of a homogeneous, initially isotropic turbulence which is subjected to a pure plane strain whose principle axes suddenly rotate a certain angle alpha in the course of a time T. Calculations are performed using Craya's model (1958) which employs a spectral tensor of double twopoint velocity correlations. Initially, triple correlations are neglected and the study is limited to a linear analysis. Attention is given to the evolution of turbulent kinetic energy, and to the evolution of the Reynolds stress tensor for alpha equals pi/2.
