Abstract: Stability analysis of buoyancy-driven convective flow in the trapezoidal cavities is essential for efficient heat transfer in solar evaporators. In the present analysis, the symmetry breakdown pitchfork and Hopf bifurcations' ...

Abstract: Rayleigh–Bénard convection (RBC) in symmetric trapezoidal closed cavities with cavity angle ϕ=70°−110°, filled with air, is studied using numerical simulations where inclined side walls are adiabatic. In contrast to ...
