Statistical Coefficients in the Equation for the Joint Probability Density of a Scalar and Its Gradient 2004 The characteristic scales, dispersions, and dissipation rates of isotropic, degenerate, turbulent velocity and scalar fields as well as several third-order moments for these fields have been determined and compared to those obtained by direct numerical simulation. These quantities determined as a time function were used to close the equation for the joint probability density of a scalar and its gradient, obtained by the authors earlier. The coefficients of this equation calculated using two models developed by the authors are in good agreement with those determined by direct numerical simulation.
