چکیده انگلیسی
The present paper investigates a promising avenue for the intensification of turbulent free convection in various configurations using adequate binary gas mixtures in which helium (He) is the primary gas component and carbon dioxide (CO2), methane (CH4), nitrogen (N2), oxygen (O2) and xenon (Xe) are the secondary gas components. In the context of binary gas mixtures, the thermo-physical properties: viscosity, thermal conductivity, density and isobaric heat capacity depend on three quantities: temperature, pressure and molar gas composition. Within the platform of turbulent free convection using the five binary gas mixtures for Ra > 109, results are presented for the allied convective coefficient hmix/B varying with the molar gas composition w in the w-domain [0, 1]. Values of the maximum allied convective coefficients hmix,max/B attained at the correlative optimal molar gas compositions wopt are easily extracted from suitable design charts.
