Abstract
Corrsin equation is closed using the gradient hypothesis relating a two-point third-order correlation moment to a two-point second-order correlation function of a passive scalar field. Based on closed system of Karman-Howarth and Corrsin equations the numerical model of turbulent temperature fluctuations dynamics in isotropic turbulent flow is developed.
