This study conducts a numerical simulation of mixed (combined) convective non-Newtonian fluid flow inside two-dimensional cavity (skewed) having moving lid. The upper and bottom extremities the with different temperatures two insulated side walls cause natural convection. Moreover, forced convection is maintained by motion lid constant velocity. governing equations are nondimensionalized approp...

Numerical simulation analyzes the mixed convection flow of $$\hbox {Al}_{2}\hbox {O}_{3}{-}\hbox {Cu}{-}\hbox {H}_{2}\hbox {O}$$ (aluminium oxide–copper–water) hybrid nanofluid inside a split lid-driven trapezoidal cavity. A triangular-shaped cold obstacle is placed The horizontal base cavity kept cold, whereas side walls are chosen adiabatic. thermally active upper wall maintained at constant ...

The motion of a finite-size particle in the cuboidal lid-driven cavity flow is investigated experimentally for Reynolds numbers $100$ and $200$ which steady. These steady three-dimensional flows exhibit chaotic regular streamlines, where latter are confined to Kolmogorov–Arnold–Moser (KAM) tori. interaction between moving wall creates global attractors. For neutrally buoyant particles, these at...

This study performs extensive numerical simulations to investigate how the aspect ratio ( AR) of a lid-driven cavity influences onset elastic instability and turbulence subsequent mixed convective heat transfer rate inside it. To this end, we utilize finite volume method based open source code OpenFOAM along with Rheotool solve mass, momentum, energy, viscoelastic constitutive equations. We fin...

An anisotropic refinement criterion suitable for Finite-Volume methods is presented and Navier–Stokes solutions are reported for the lid-driven cavity flow configuration at Re 1⁄4 1000 with adaptive anisotropic meshes (h-refinement). The a posteriori error estimation criterion is based on the assessment of the goodness-of-fit of the least squares regression used to perform the variables profile...

Incompressible Navier-Stokes solvers based on the projection method often require an expensive numerical solution of a Poisson equation for a pressure-like variable. This often involves linear system solvers based on iterative and multigrid methods which may limit the ability to scale to large numbers of processors. The artificial compressibility method (ACM) [6] introduces a time derivative of...

Chaperonins use ATPase cycling to promote conformational changes leading to protein folding. The prokaryotic chaperonin GroEL requires a cofactor, GroES, which serves as a "lid" enclosing substrates in the central cavity and confers an asymmetry on GroEL required for cooperative transitions driving the reaction. The eukaryotic chaperonin TRiC/CCT does not have such a cofactor but appears to hav...

The Lattice Boltzmann Method is applied to incompressible, steady, laminar flows at high Reynolds numbers varying in a range form 50 to 2000. The developing channel flow and the lid driven cavity flow are analyzed. The effect of the model Mach number on accuracy is investigated by performing computations at different Mach numbers in the range 0.1 0.4 and comparing the results with finite-volume...
