Periodic motion of three stirrers in a two-dimensional flow can lead to chaotic transport of the surrounding fluid. For certain stirrer motions, the generation of chaos is guaranteed solely by the topology of that motion and continuity of the fluid. Work in this area has focused largely on using physical rods as stirrers, but the theory also applies when the “stirrers” are passive fluid particl...

In this work, the effect of a variable spatial magnetic field on ferro-nanofluid flow and heat transfer in a double-sided lid-driven enclosure with a sinusoidal hot wall is investigated. The working fluid is a mixture of iron oxide (Fe3O4) nanoparticles and water and is referred to as a ferro-nanofluid. The control volume-based finite element method (CVFEM) is used to solve the governing equati...

Levodopa remains the mainstay of treatment for Parkinson disease (PD), but its use is associated with dyskinesias (LID) in many patients. LID likely reflect dysregulated release of dopamine combined with altered postsynaptic mechanisms due to pulsatile dopamine receptor stimulation. Dopamine D receptors are increased in animal models of LID, and experimental LID is attenuated by suppression of ...

Swarms of police drones, fleets of overhead delivery bots, and flocks of private security drones are set to multiply the complex interfaces between state, capital, and sense. This paper explores the military and economic enclosure of the atmosphere by drones. For centuries, capitalist enclosure has privatized and secured common spaces: territorializing new power relations into the soil. Enclosu...

In this study, a numerical solution of 2D steady incompressible lid-driven cavity flow is presented. Three different numerical schemes were employed to make a comparison on the practicality of the methods. An alternating direction implicit scheme for the vorticity-stream function formulation, explicit and implicit schemes for the primitive variable formulation of governing Navier-Stokes equatio...

The lid-driven cavity is an important fluid mechanical system that serves as a benchmark for testing numerical methods and studying fundamental aspects of incompressible flows in confined volumes. These are driven by the tangential motion bounding wall. This article presents complete study flows, with primary focus being placed on development flow when Reynolds number was increased. In order to...

Analysis of lid driven square cavity flow air with three different ranges Ri and Re are analyzed using numerically. Adiabatic temperature is maintained at horizontal walls isothermal established the vertical in which top wall assumed to slide a uniform speed. Finite volume method techniques have used solve non dimensional governing equations. To visualize thermal characteristics, control parame...
