| Summary: | The results of testing of several RANS turbulence models on a problem of free convection near a suddenly heated infinite vertical plate based on comparison with classic literature data are presented. Numerical solutions were obtained using four turbulence models, two of which are based on the isotropic turbulent viscosity concept and the use of the other two involves solving the transport equations of the Reynolds stress tensor components. The characteristics of the flow and heat transfer for different stages of boundary layer development, from laminar to turbulent, are presented. Based on a comparison with the literature data, conclusions are drawn about the predictive capabilities of the turbulence models considered.
