Abstract

A free-convective turbulent boundary layer on a vertical isothermal surface is examined. The influence of the buoyancy force on the kinetic energy of the turbulent fluctuations is analyzed. A modification is proposed for the turbulence model that takes account of the free-convective flow singularities.
