  • By analyzing the components of Reynolds stresses of implicit algebraic stress model(IASM) in this paper,that Reynolds stresses in buoyant turbulent flows were produced by both strain and buoyancy is considered.Consequently,a nonlinear anisotropy buoyant turbulence model was developed by applying linearity of equilibrium hypothesis to Reynolds stress transports.The model avoids numerical singularity and its reliability is verified by the comparisons between predictions and experimental data.
