In this paper, we present numerical results obtained by an in-house incompressible fluid flow solver based on isogeometric analysis (IgA) for the standard benchmark problem simulation – lid-driven cavity flow. The steady Navier-Stokes equations are solved in their velocity-pressure formulation and consider only inf-sup stable pairs of B-spline discretization spaces. main aim paper is to compare...

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...

This paper deals with the design and implementation of cross-platform, D2Q9-BGK D3Q27-MRT, lattice Boltzmann method solver for 2D 3D flows developed ArrayFire library high-performance computing. The leverages ArrayFire’s just-in-time compilation engine compiling high-level code into optimized kernels both CUDA OpenCL GPU backends. We also provide C++ Rust implementations show that it is possibl...

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 ...
