The Lagrangian transport in the laminar incompressible flow a two-dimensional square cavity driven by harmonic tangential oscillation of lid is investigated numerically for wide range Reynolds and Strouhal numbers. topology fluid trajectories analyzed stroboscopic projections revealing co-existence chaotic regular Kolmogorov–Arnold–Moser (KAM) tori. pathline structure strongly depends on number...

In this article, a complex nature structure is simulated by introducing the nanofluid that contains various shape of nanoparticles through forced convection and thermal diffusion. Double sided lid-driven in porous curved cavity dealt to handle phenomenon. Additionally, effect internal heat generation/absorption also considered. The horizontal vertical walls are moving with constant speed Uo Vo,...

Viscoelastic flow in a square cavity is studied in detail for the FENE-CR model with a given value of extensibility. A finite volume method was employed to predict both the steady flows resulting from movement of the top cavity wall and also the recoil flows that follow the cessation of that lid-wall motion, when the fluid possesses viscoelastic properties. It is shown that this recoil flow can...
