  We construct a new subgrid scale (SGS) stress model for representing the
small scale effects in large eddy simulation (LES) of incompressible flows. We
use the covariance tensor for representing the Reynolds stress and include
Clark's model for the cross stress. The Reynolds stress is obtained
analytically from Cinlar random velocity field, which is based on vortex
structures observed in the ocean at the subgrid scale. The validity of the
model is tested with turbulent channel flow computed in OpenFOAM. It is
compared with the most frequently used Smagorinsky and one-equation eddy SGS
models through DNS data.
