In this study, the numerical investigation of Al 2 O 3 -Water nanofluid mixed convection in a T-shaped lid-driven cavity presence thermal barrier with positioning at different positions is investigated by two-phase mixture model. Variable parameters study are aspect ratio (AR), volume fraction nanoparticles ( ? ), Richardson numbers (Ri), and placements cavity. The results indicated that increa...

This paper investigates a polygonal finite element (PFE) to solve two-dimensional (2D) incompressible steady fluid problem in cavity square. It is well-known standard benchmark (i.e., lid-driven flow)-to evaluate the numerical methods solving problems controlled by Navier–Stokes (N–S) equation system. The approximation solutions provided this research are based on our developed equal-order mixe...

the effects of single walled carbon nanotube (swcnt) on mixed convection in a cavity are investigated numerically. the problem is studied for different richardson numbers (0.1-10), volume fractions of nanotubes (0-1%), and aspect ratio of the cavity (0.5-2.5) when the grashof number is equal to 103. the volume fraction of added nanotubes to water as base fluid are lowers than 1% to make dilute ...

This paper presents a numerical investigation of the laminar mixed convection flow of a radiating gas in an inclined lid-driven cavity. The fluid is treated as a gray, absorbing, emitting, and scattering medium. The governing differential equations including continuity, momentum and energy are solved numerically by the computational fluid dynamics techniques (CFD) to obtain the velocity and tem...

the fluid flow and heat transfer in lid-driven enclosures filled with cu-water nanofluid is numerically investigated. the moving vertical walls of the enclosure  are maintained in a constant temperature, while the horizontal walls are insulated. the hybrid scheme is used to discretize the convection terms and simpler algorithm is adopted to couple the velocity field and pressure in the momentum...
