MHD mixed convection of nanofluid in a flexible walled inclined lid-driven L-shaped cavity under the effect of internal heat generation

摘要: Abstract In this study, mixed convective flow of nanofluid in an inclined L-shaped cavity which has elastic walls is numerically analyzed under the effects internal heat generation and magnetic field by using finite element technique with Arbitrary-Lagrangian–Eulerian method. Simulations are performed for different values Richardson number (between 0.03 30), inclination angle 0°and 180°), Hartmann 0 50), orientation 90°), Rayleigh 1 4 6 ), solid nanoparticle volume fraction 0.04), flexible wall modulus 8 ) aspect ratio 0.2 0.7) cavity. It was observed that on transfer features significant lowest value while 11% discrepancy obtained average Nusselt when rigid compared. The impact compared to strength variation number. Cavity impacts water nanofluid. A higher size cold (aspect ratio) increases rate reduces it. Enhancement about 15%–19% at highest trends respect changes pertinent parameters similar
