Direct numerical simulations of Rayleigh-Bénard convection of a gas-liquid medium near its density maximum

•Rayleigh-Bénard convection in the oxidation of hydrocarbons process is simulated.•Density inversion phenomenon plays a role of enhancing the stability of convection.•Flow pattern evolution strongly relies on the density inversion parameter.•A scaling relationship for average Nusselt number is succe...
