The results show that, above a certain Reynolds number, the hairy flaps lead to a jump in the vortex shedding frequency.
Bubbles that cause vortex shedding will lead to a significantly higher conversion per volume than spherical bubbles.
For the Newtonian fluid, a corner vortex is found upstream of the contraction and increasing flow inertia leads to a reduction of the vortex size.
We show that the shear-thinning effects of both the viscosity and the elasticity of a fluid may lead to double-vortex flows.
leads to a change in the leading edge vortex (LEV) and spanwise flow structures, which impacts the aerodynamic force generation.
Increasing the elasticity of the flow, while still maintaining low inertia flow conditions, leads to a strong increase of the vortex size, until an elastic instability sets in and the flow becomes time-dependent at De≈200, 300, 70 and 450 for CR=2.4, 4, 8 and 12, respectively.
The changes of the middle chamber size lead to multi-staging vortex inside the combustor.
This is demonstrated for spatially developing mixing layers which lead to vortex roll-up and ligaments, prior to droplet formation.
The coherent effects further downstream lead to more complex vortex patterns in the far wake.
In superconducting thin films, engineered lattice of antidots (holes) act as an array of columnar pinning sites for the vortices and thus lead to vortex matching phenomena at commensurate fields guided by the lattice spacing.
