Sureshkumar, P. Gokulavani, Ali J. Chamkha This is a preprint; it has not been peer reviewed by a journal. https://doi.org/ 10.21203/rs.3.rs-7229771/v1 This work is licensed under a CC BY 4.0 License Status: Posted Version 1 posted You are reading this latest preprint version Abstract Our present focus is on studying thermosolutal convection in a hybrid nanofluid saturated ventilated porous chamber, taking into account radiation and oblique Lorentz force as extra factors. The research is conducted using a hybrid nanofluid that consists of water and nanoparticles of copper and alumina. The non-oscillatory heating is provided by two vertically placed baffles that are centered in the porous container. The goal of this research is to determine the impact of radiation on the hybrid nanofluid and porous medium’s unique properties, as well as the tilted magnetic field effects, on the heat transfer and flow patterns within the cavity. We apply the finite difference approach to solve the discretized governing equations and boundary conditions. The numerical findings are analysed in relation to a number of properties, such as buoyancy ratio, Lewis number, Hartman number, inclined magnetic field, heat radiation, Darcy number, and solid volume percentage. A magnetic inclination parameter is also taken into account. The N u goes down as Le goes up at Ra = 10 5 , but it stays the same at Ra = 10 3. When Br + , convection is improved and N u is increased. However, when Br − , heat transport is limited and convection is weaker. For all inclination angles, Sh increases in response to Ha; however, the rate of growth is significantly affected by λ. The effects of Ra and Le on mass transfer (Sh) are more significant than those on heat transfer (N u), although the effects of Le and φ on both thermal and mass transfer are separate.
