要約

A multi-equation turbulence model for free-convective boundary layer near a vertical flat plate is developed. Attention was specially paid to description of the mean squared temperature fluctuations and correlation of fluctuations of longitudinal velocity and temperature. An algebraic relation taking account of specific features of a free-convective flow was used to model the projection of a turbulent heat flux into a normal to a solid surface. The numerical results obtained are in good agreement with experimental data.
