Analysis and reformulation of the -- turbulence model for buoyancy-driven thermal convection
Da-Sol Joo
The representation of buoyancy-driven turbulence in Reynolds-averaged Navier--Stokes (RANS) models remains unresolved, with no widely accepted standard formulation. A key difficult…

A global similarity correction for the RANS modeling of natural convection in unstably stratified flows
Da-Sol Joo
This study proposes a global similarity correction for Reynolds-averaged Navier--Stokes (RANS) modeling of buoyancy effects in unstably stratified flows. Conventional two-equation…
