O. F. Voropaeva Institute of Computational Technologies, Russian Academy of Sciences, Novosibirsk, Novosibirsk State University, Novosibirsk
Abstract:
Modified two-equation turbulence models based on a more thorough parameterization of buoy- ancy effect in the coefficients of turbulent viscosity and diffusion were developed. The models were tested on the problems of free turbulence dynamics in stably stratified media in two- and three-dimensional parabolized problem statements.
Keywords:
two-equation turbulence models, stable stratification, stability function, turbulent wake, turbulent spot, pycnocline.
