Rayleigh drag
WebInstead of a boundary-layer scheme, a Rayleigh drag is applied at the model's bottom boundary to represent dissipative processes in the interior. This drag extends over all latitudes in the test case but can also be applied only over a chosen range of latitudes. WebTaylor-Couette flow, the flow between two coaxial co- or counter-rotating cylinders, is one of the paradigmatic systems in the physics of fluids. The (dimensionless) control parameters are the Reynolds numbers of the inner and outer cylinders, the ratio of the cylinder radii, and the aspect ratio. One key response of the system is the torque required to retain constant …

WebApr 12, 2024 · The SAW action on droplets is attributed to two forces: the drag force caused by the acoustic radiation force (ARF) and the acoustic streaming force (ASF) ... Video S1: Simulation results of SAWs propagating in the form of Rayleigh angles inside droplets (2D), and SAWs forming swirl-like acoustic pressure inside droplets (3D). WebEffects of drag, lift, thermophoresis and Brownian forces on the particle trajectories were investigated. It was observed that the variation of Rayleigh number can significantly change the flow field and the corresponding particle deposition patterns. In particular, recirculation regions were formed near the corners as the Rayleigh number ...

If a moving fluid meets an object, it exerts a force on the object. Suppose that the fluid is a liquid, and the variables involved – under some conditions – are the: speed u,fluid density ρ,kinematic viscosity ν … See more In fluid dynamics, the drag equation is a formula used to calculate the force of drag experienced by an object due to movement through a fully enclosing fluid. The equation is: • See more The drag force can also be specified as See more • Aerodynamic drag • Angle of attack • Morison equation • Stall (flight) • Terminal velocity See more The equation is easier understood for the idealized situation where all of the fluid impinges on the reference area and comes to a complete stop, building up stagnation pressure over the whole area. No real object exactly corresponds to this behavior. See more To empirically determine the Reynolds number dependence, instead of experimenting on a large body with fast-flowing fluids (such as real-size airplanes in wind tunnels), one may just as well experiment using a small model in a flow of higher velocity … See more • Batchelor, G.K.
