This paper describes an improved decoupling algorithm for calculating low Mach number near-critical fluid flows, in which thecp-formulation of the energy equation is used (cprefers to the specific heat at constant pressure) and the pressure–velocity coupling is treated through the block-coupled method, together with a transformation of the continuity equation. The algorithm is validated by a 2D near-critical CO2Rayleigh–Bénard convection problem. After the mesh and time step independence studies, the correctness is presented through the stability behaviors of the hot boundary layer under different heating intensities and the typical evolution of the temperature field. The improved decoupling algorithm owns a better stability and can further reduce the CPU time. The advantages are even more obvious when the flow is convection-dominated.
