A numerical simulation of plane turbulent shear layer
Abstract
A numerical simulation for a plane turbulent shear layer is worked out by means of the large-eddy simulation. Initial fields are assumed to be a superposition of the mean velocity (of error-function type) with isotropic or nonisotropic three-dimensional turbulence. The effects of the intensity as well as the nonisotropic property of the initial turbulence are examined along with various sizes of computational domain. The results are in reasonable agreement, at least qualitatively, with some of the experimental evidence for an appropriate choice of initial turbulence.
