<abstract> <p>Double diffusive natural convection (DDNC) is one of the most studied phenomena in convective energy transfer, having applications heat exchangers, oceanography and climate Science, biological Systems, renewable energy, geothermal systems. We aimed to conduct a numerical analysis DDNC within quadrantal enclosure that contained Cu-Al<sub>2</sub>O<sub>3</sub> hybrid nanofluid with water as host fluid. The motivation for choosing this model was attributed relatively limited research conducted particular geometric configuration, specifically context double-diffusive convection, which served primary mode mass transfer. Using simulations, we focused on impacts an external magnetic field. bottom wall cavity kept at high temperatures $ {(T}_{h}) concentrations {(c}_{h}), $while vertical maintained low {(T}_{c}) $and {(c}_{c}) $. Moreover, curved thermally insulated. With eminent method, finite element method employed solve governing partial differential equations (PDEs), are transformed into dimensionless form. outcomes were acquainted streamlines, isoconcentration contours, isotherms, along local average Nusselt Sherwood numbers. revealed enhancing volume fraction nanoparticles conventional fluid increased transfer efficiency by up 11% compared base It also noticed without field (Ha = 0), stream functional measures its highest value {(\psi }_{max} 6.2) indicated strong convection. However, presence 40), function significantly decreased 0.2) $.</p> </abstract>
