The buoyancy force and flow acceleration effects of supercritical CO2 on the turbulent heat transfer characteristics in heated vertical helically coiled tube

•The buoyancy parameter ϕ2 is proposed to quantified analysis buoyancy effect.•Flow acceleration plays a role in the heat transfer deterioration at q+ > 4.5 × 10−4.•The buoyancy factor Fb and acceleration factor Fac are proposed.•A new correlation is proposed for supercritical CO2 in helically co...
