Double-diffusive mixed convection in a lid-driven square enclosure filled with Al2O3-water is numerically investigated. Two-dimensional nonlinear governing equations are discretized using the control volume method and hybrid scheme. The equations are solved using SIMPLER algorithm. The results are displayed in the form of streamlines, isotherms, and iso-concentrations when the Richardson number...

Mixed convection of Cu-Water nanofluid is studied numerically in a shallow inclined enclosure by applying lattice Boltzmann method. The D2Q9 lattice and internal energy distribution function based on the BGK collision operator are used in order to develop the thermal flow field. The enclosure's hot lid has the constant velocity of U0 while its cold lower wall has no motion. Moreover, sidewalls ...

Abstract The impacts of MHD and heat generation/absorption on lid‐driven convective fluid flow occasioned by a square enclosure housing an elliptic cylinder have been investigated numerically. the horizontal boundaries were insulated left vertical wall was experienced at fixed hot temperature, right exposed to cold temperature. COMSOL Multiphysics 5.6 software used resolve nondimensional equati...

In this work, a 19-bit Incompressible Generalized Lattice Boltzmann (IGLB) method has been proposed for threedimensional incompressible fluid flow simulation, for the first time. Equilibrium moments in moment space are derived from an incompressible BGKLB method. The incompressible Navier–Stokes equations can be recovered through the Chapman-Enskog multi-scale expansion without artificial compr...

The current study explores numerically mixed convection of thermo-dependent power-law fluids in a square lid-driven enclosure, including the thermal radiation effect. vertical sidewalls are sustained at both hot and cold temperatures. On other hand, cavity is insulated from horizontal walls. upper wall moving along x-axis. main governing equations that Boussinesq approximation used for solved u...
