Vortex VTX400P inline blower for 4 inch diameter duct has a built in automatic pressure switch that detects when air is flowing through the duct. It will automatically turn on and off the booster fan as required. In a clothes dryer application, when the dryer goes on, the VTX400P will automatically turn on and stay on until after the dryer goes off. This allows the dryer to perform more efficiently. Both drying time and power consumption are reduced.
At the end of each stroke in one heaving period as shown in figure 3(a), one primary LEV and a minor LEV are shed. The primary LEV is formed by the rolling up of separated shear layer, and it induces a secondary vortex, i.e., the region with red color beneath it. The secondary vortex cuts off the shear layer that feeds the primary LEV at the decelerating phase, with the remaining shear layer rolling into a minor LEV. The minor LEV is shown by the blue region upstream of the primary one. This minor LEV is usually very weak, so only the main LEV is considered. The formation of LEV is important for thrust. Wang8 illustrated that no thrust would be produced if the heaving amplitude is too small to form the LEV. Also one TEV is shed in each stroke, but it is quickly advected downstream.
During the stroke with the occurrence of PO-LEV, vorticity in the secondary vortex in figure 3(a) merges with the newly formed LEV in figure 3(b). After the PO-LEV passes over the leading edge, it couples with the newly formed LEV to form a vortex pair. This vortex pair has different behavior compared with one single LEV, and it departs from the airfoil more quickly, making the newly formed LEV in it unable to pass over the leading edge again in most situations. As a result, when the PO-LEV occurs, the symmetry of upstroke and downstroke is generally broken, and the wake flow is also more likely to become chaotic, as shown in figure 5(b). Only at small frequencies, such as the case in figure 5(a), the periodicity may remain with the period being multiplied, see also Ref. 10.
In general, at fixed amplitude the higher the heaving frequency, the larger the mean thrust is, except for the case with Sta = 0.434, Ac = 3/4 in which the vortex from upstream interacts with and strengthens the TEV resulting in a very strong TEV and a high drag. CL on the other hand is mainly contributed by the added-mass force, which is proportional to Ayf2. Since vB0 is proportional to Ayf, the power consumption is proportional to Ay2f3 which grows very fast as f. But the growth of mean thrust with f is relatively slow, so the efficiency decreases at very high frequencies.
The evolution of vortex center with l is shown in figure 10(a) and (b). The LEV moves almost at a constant velocity, which varies with different AoAs. Γ evolving with l is shown in figure 10(c), and it also grows almost linearly. A set of scaling laws can be found,
The distribution of 2Qϕ1 in the thrust-generating stage is shown in figure 14(a). The vortex core of the LEV contributes thrust while that of the TEV contributes drag. The flow surrounding the vortex core is also important, but plays an opposite role. The same result is also shown in figure 14(b) with a much smaller contour range, indicating that the attached boundary layer is not an important source of Fpx. This is in accordance with the boundary layer theory which says the attached boundary layer cannot change the external pressure significantly.
which is also presented in figure 14. The negative PoCi means thrust and the positive one is drag. The volume integral of 2Qϕ1 contributes 104% thrust in total and Fpx,vis together with viscous force generates 4% drag. The vortex core of the LEV is the most important source of thrust, while the TEV contributes a dramatic drag. Surrounding the LEV, the region with large strain rate contributes also a significant drag. These explanations to the roles of LEV and TEV are consistent with those given by Martín-Alcántara et al.,10 however, the suction force from the vortex core is more clearly revealed in the WPS theory compared with the force element theory where the vortex core shows a repulsive effect sometimes.10
In the single-stroke motion, large σ peaks exist around the sharp edges at the staring phase, see figure 15(a). On the lower surface, the negative σ peak at the leading edge generates the vorticity in the LEV and the positive σ peak at the trailing edge creates the vorticity in the TEV. On the upper surface near the leading edge, a positive σ peak exists which reflects the adverse pressure gradient in the boundary layer. This positive σ produces positive vorticity beneath the boundary layer resulting in a bubble which lifts up the boundary layer and makes it separate. The separated shear layer at the leading edge then rolls up into an LEV (see figure 13(b)), which in turn enhances the adverse pressure and the bubble resulting in a secondary vortex. The enhancement effect of LEV on the secondary vortex can be seen by the σ peak and low pressure in figure 15(b) at Y = 0.043.
Four time steps are picked out at t/T = 9.000, 9.108, 9.212, 9.403, see the grid lines in figure 16, with the corresponding vorticity fields given in figure 17. At time t/T = 9.000 when the airfoil has the maximum transversal velocity, the PO-LEV contacts the body at the leading edge, and the transient thrust is also maximized. After the PO-LEV passes over the leading edge, it couples with a newly formed LEV to form a vortex pair. This vortex pair rotates with a relatively large radius and finally hits the airfoil again. The rotation of vortex pair can be understood by the point vortex model as sketched in figure 18.
Vorticity fields for the four time steps in figure 16. (a) t/T = 9.000, (b) t/T = 9.108, (c) t/T = 9.212 and (d) t/T = 9.403. V1 denotes the PO-LEV and V2 the newly formed LEV. Dashed circle in (b), (c) and (d) shows approximately the rotating path of the vortex pair.
Two flow types are associated with large transient thrust. The first is at t/T = 9.000 when the PO-LEV reaches the leading edge resulting in two vortices around the leading edge, and the second is at t/T = 9.403 when the rotating vortex pair hits the wall.
The force coefficients and vortex shedding Strouhal number are shown in Table II. When the multipole method is not used, the maximum lift, mean drag and Sts decrease slowly with R. However, with the MBC, the results converge fast, and good accuracies in these quantities are achieved with a quite small R. The present results also agree well with the data from Ding et al.37 and Wang et al.38 The vorticity fields with and without MBC are shown in figure 23. The vorticity field near the outer boundary is much cleaner when the MBC is adopted.
Increasing energy costs justify research on how to improve utilization of low-grade energy that is abundantly available as waste heat from many thermodynamic processes such as internal combustion engine cycles. One option is to directly generate cooling through absorption/adsorption or vapor jet ejector cycles. As in the case of power generation cycles, cooling cycle efficiencies would increase if the heat input were available at higher temperature. This paper assesses the feasibility of a novel idea that uses a vortex tube to increase the available temperature levels of low-grade heat sources. The desired temperature increase is achieved by sending a stream of vapor that was heated by the waste heat source through a vortex tube, which further elevates the temperature used in a heat driven ejector cooling cycle. Simulation results show that COP can be increased by 40% with the use of the vortex tube heat booster when the cycle is operating with low entrainment ratio at conditions where baseline performance and COP are low.

As a polar vortex rips through America, train tracks are ablaze and door hinges are freezing indoors. Yet amidst this icy mayhem is fascinating atmospheric science. Just how does frigid air from the Arctic become displaced by hundreds and even thousands of miles? Here are a few of the best visualizations revealing the origins and monumental planetary scale of this extreme weather event.
This disruption let warmer air move north, making way for a whoosh of winter to obliterate some Americans hopes of never having to experience a -60 degree day. Stratospheric filaments stretching high into the atmosphere can swing loose, leading the way for stinging cold and extreme winds. Serra et al.'s "Uncovering the Edge of the Polar Vortex" in the Journal of the Atmospheric Sciences reveals an astounding 3-D view of the now familiar polar vortex.
The vortex may yet be most intuitive to visualize when shown as a flat animation atop our globular planet. To that end, Joshua Stevens of the NASA Earth Observatory produced an animation showing a swoop of boreal winds carrying Arctic vibes into middle latitudes.
