Abstract: A numerical model of the dynamics of turbulence and temperature fluctuations behind a heated grid located in a wind tunnel is constructed on the basis of closed Kármán–Howarth and Corrsin equations. Results calculated by this model are in reasonable agreement with available experimental data.

Keywords: Kármán–Howarth and Corrsin equations, turbulence behind a grid, isotropic turbulence, turbulent fluctuations of temperature, numerical modeling.
