Abstract

Engineering Engineering, Mechanical Physical Sciences Science & Technology Technology Thermodynamics
Numerical Simulations of heat and mass transfer in supercritical carbon dioxide are carried out for natural convection conditions in a differentially heated square enclosure. The two vertical walls are maintained at different temperatures while the two horizontal walls are insulated. For the mass transfer studies, a heated vertical naphthalene wall is considered. Properties of supercritical carbon dioxide are evaluated from the National Institute of Standards and Technology (NIST) Standard Reference Database 12. A correlation for the mean Nusselt number along the heated wall is obtained as a function of the heat transfer Rayleigh number (for a given Prandtl number). A correlation for the temporal Sherwood number along the naphthalene surface is obtained as a function of the mass transfer Rayleigh number, and Fourier number (for a given Schmidt number). The results are compared with result available in the literature.
