Successive bifurcations in a fully three-dimensional open cavity flow

Three-dimensional Flow in Cavity at Yaw

This study is motivated by three-dimensional ows about protrusions and cavities with an arbitrary angle between the external ow and rigid elements. The novel type of a \building block" cavity ow is proposed where the cavity lid moves along its diagonal (Case A). The proposed case is taken as a typical representative of essentially three-dimensional highly separated vortical ows having simple si...

Three-dimensional flow instabilities in a thermocapillary-driven cavity.

A linear stability analysis of the buoyant-thermocapillary flow in open rectangular cavities with aspect ratios in the range Gamma=1.2 to 8 is carried out for Prandtl number Pr=10 and conditions of previous experiments. The results are in very good agreement with most available experimental data. The energy transfer between the basic and the perturbation flow reveals that buoyancy is not direct...

Heat Transfer in Three-Dimensional Flow along a Porous Plate

An analysis of heat transfer in the flow of a viscous, in-compressible fluid along an infinite porous plate is presented when the plate is subjected to a transverse sinusoidal suction. The flow field becomes three-dimensional due to this type of suction velocity. Expressions for the flow and temperature fields are obtained by series expansion method. It is found during the course of discussion ...

Bifurcations to three-dimensional flows in a periodically driven cylindrical cavity

Consider a Newtonian fluid of kinematic viscosity ν and density ρ confined in a finite cylinder of radius R and height H, whose sidewall oscillates harmonically in the axial direction, with period T and maximum axial velocity Vmax, while the top and bottom lids remain at rest. There are three non-dimensional parameters in this problem: the aspect ratio, Γ = H/R, the Reynolds number, Re = VmaxR/...
