Vortex generator axial

At twist, a stream by means of axial vortex generator with flat or profiles blades hydraulic resistance, depends only on average speed of gas in cracks between blades and their forms. Hydraulic resistance vortex generator with flat blades in 1.5 times above, than with profiles that speaks reduction of losses an input entrance in the device and various conditions of movement of a stream between plates (Kutepov, 1977).

Swirl-flow devices include a number of geometric arrangements or tube inserts for forced flow that create rotating and/or secondary flow inlet vortex generators, twisted-tape inserts, and axial-core inserts with a screw-type winding.

For a supply of a liquid in a zone of contact, it is offered to use hollow blades axial, conic, or tangential vortex generator [12002D19]. But, they are complex difficult in manufacturing and reduce relative section vortex generator that limits area of their application. Diameter and height of contact branch pipes essentially influence metal consumption of the device and efficiency mass transfer. For an intensification mass transfer in a number of designs (wed), it is offered to put render on a surface... 

Increase of efficiency dust separation is caused by installation in the device of the axial sprinkler punched by apertures of small diameter, placed on a screw line. Apertures are executed in such a manner that the jet of a liquid from them is directed tangential to a surface of an axial sprinkler. The comer of an inclination of a jet is provided with directing plugs, compaction in apertures of an axial sprinkler. Thus due to impact following under a pressure the spiral film-drop liquid veil is formed of apertures of an axial sprinkler of liquid jets with a peripheral edge of blades vortex generator. 

Before vortex generator 5, the axial branch pipe 10 supplies of a liquid is placed, at a level top cut, which the basis conic dissector 7 is located with a backlash. On an output exit of a gas stream are stipulated drip pan 11. Vortex generator 5, it is fixed on a rotor 12, which is resulted brought in rotation by the electric motor through a belt drive 13. 

The Gas stream containing mechanical or gaseous impurity, acts on a tangential branch pipe 3 in the ring space formed by the case 1 and rotor 12. The liquid acts in the device by means of an axial branch pipe 10. Owing to that die axial branch pipe 10 supplies of a liquid is placed before vortex generator 5, at dispersion liquids the zone of contact of phases increases and, hence, the effective utilization of working volume of the device takes place more. 

Under low-frequency excitation, the flame front is wrinkled by velocity modulations (Fig. 5.2.5). The number of undulations is directly linked to frequency. This is true as far as the frequency remains low (in this experiment, between 30 and 400 Hz). The flame deformation is created by hydrodynamic perturbations initiated at the base of the flame and convected along the front. When the velocity modulation amplitude is low, the undulations are sinusoidal and weakly damped as they proceed to the top of the flame. When the modulation amplitude is augmented, a toroidal vortex is generated at the burner outlet and the flame front rolls over the vortex near the burner base. Consumption is fast enough to suppress further winding by the structure as it is convected away from the outlet. This yields a cusp formed toward burnt gases. This process requires some duration and it is obtained when the flame extends over a sufficient axial distance. If the acoustic modulation level remain low (typically v /v < 20%),... 

In the case of more or less axially mounted stirrers in vessels without baffles, the liquid is set in rotation, and generates a liquid vortex. As long as the vortex is not so deep that gas can be entrained by the stirrer, the vortex depth has no influence either on the stirrer power or on the mixing process. Naturally, the power number Ne and the mixing number nO depend upon whether the stirred tank is provided with baffles or not (see Fig. 1.36 and 3.3). 

Now let us suppose that a vertical magnetic dipole is located on the borehole axis and the medium possesses axial symmetry (Fig. 3.4). In accord with the Biot-Savart law the current of the magnetic dipole creates the primary magnetic field and its change with time generates the primary vortex electric field. Due to the axial symmetry this electric field does not intersect boundaries between media with different conductivities. Because of this no electric charges develop and as a result of the existence of the vortex electric field currents arise at every point, of the conductive medium with a density given by ...

Variations in flow patterns for axial flow impellers can be generated to advantage by changing the impeller position or by baffling. For example, axial flow impellers provide radial flows when placed near the tank bottom. For submergence of floating solids, the tank is often unbaffled in the top half to create a controlled vortex useful for pulling down solids. The same method can also be used for surface inducement of gas from vapor space (Oldshne, 1983) and...
