After mixing vigorously for three cycles of 1 min, using a vortexer (Vortex Genie-2, Scientific Industries Inc., Bohemia, NY, USA), the suspension was subjected to centrifugation at 10,000 ×g, at 4°C for 45 min.
The proposed method enables accurate and smooth recovery of the vorticity and does not require explicit use of vortex images or occasional re-meshing.
Results indicate that high surface temperature on the prism promotes the onset of the Karman street, suggesting design guidelines for micro-channel based heat sinks that make use of vortex promoters.
The residue was reconstituted in methanol (1 mL and 0.75 mL for the API2000 and API3000, respectively), by use of vortex mixing and ultrasonication (5 min).
Then 5 mL of 2%Na2CO33 in 0.1 N NaOH was added and mixed using vortex mixer (Vortex Mixer, VOU1, Ratek Instruments Pty Ltd., Australia).
Perhaps the most radical concept in tidal power is the use of vortex-induced vibrations the same phenomenon that toppled the Tacoma Narrows Bridge in 1940 to generate power.
Flow controllers can be used for suppression of vortex shedding behind the cylindrical structures.
In this paper, an approximate method for determination of the induced velocity from highly anisotropic vorticity blobs is presented, and issues related to use of anisotropic elements in calculations with vortex blob algorithms for high Reynolds number near-wall flows are examined.
The analysis shows the possibility of using the vortex or disk pumps in TPTCS of information support space vehicles.
General Fusion, which uses a vortex of molten lead and lithium to contain the plasma, is backed by Amazon's Jeff Bezos.
