Description/Abstract Numerical experiments were conducted to study the natural convection in a stably stratified salt water solution with lateral heating in a square rectangular enclosure.^The method of investigation employed is the finite-difference solution of the basic conservation equations for a two-dimensional, laminar, unsteady double-diffusive convection, and calculation is made for 1.0 {times} 10{sup 5} {le} Ra{sub T} {le} 1.0 {times} 10{sup 6} and O {le} N {le} 15.^Four distinct flow regimes are observed depending on the magnitude of solutal stratification relative to thermal buoyancy N; unicell flow regime for N = 1, fully developed flow regime for N = 3, layered flow regime with the stagnant core for N = 5, the stagnant flow regime for N = 7. Formation of layered flow structure with time and the corresponding temperature and concentration distributions are examined.^Due to the double-diffusive nature of heat and salt, interesting temperature and concentration profiles are obtained in each flow regime.
