We discovered that such kind of reversed swirl flow would enhance the magnitude of main swirl flow vorticity.

Scientists form Ohio University unprecedentedly invented a tornado vortex simulator(TVS), which was famous for its convenience in controlling the magnitude of vorticity inside the simulator.[1] Fig.1 TVS swirler developed by Ohio university Afterwards, Canadian research Pooyan Hashemi Tari (2009)measured the internal pressure and velocity distribution of the vortex created by the TVS.
The fluid dynamics equations of SST turbulent model are listed as follow: (1) (2) During these equations, stands for turbulent energy,is equation .

Fig. 1.
In the literature, the vast majority of theoretical and experimental works, which deal with the microstructural evolution, have been investigated for binary alloys [1-12] and almost nothing for ternary alloys [13-16].
As can be seen by Fig. 4 the variation of HV on l1 and l1-1/2 can be represented by power and Hall-Petch type equations gives by HV=3926(l1)-0.6 and HV=-113.8 + 4067.3(λ1)-1/2, respectively.

Bi2Te3 bulk materials were prepared by combining chemical bath method and hot pressing at 80 MPa and 375 oC for 1 h.
Fig.1 Standard data of Bi2Te3 (JCPDS card 15-0863) (a), typical X-ray diffraction pattern of bulk I (b) and bulk II (c).
The bulks consist of randomly oriented plate-like grains (about 1 μm big and a few hundreds nm thick).

However, the actuation strain observed was very small around 10ppm which was 1/1000 times lower than the calculated value.
A representative FSMA is NiMnGa, and 0.2% magnetic-field-induced strain (MFIS) was firstly reported by Ullakko et al. [1, 2].

The second charge and discharge capacities were ~63 and ~43 mAh g–1 in propylene carbonate-based electrolyte and ~86 and ~60 mAh g–1 in ethylene carbonate-based electrolyte, respectively.
As shown in Fig. 1 (a), a flat plateau was observed at ~ 0.88 V during first charging, whereas it was observed at ~0.79 V in Fig. 1 (b).

The XRD patterns of AlN-Mo composite with hot pressed sintering is shown in Fig.1.
Mo2C has a melting point of 2520˚C, a thermal conductivity of 21.5 W·m-1·K-1 and an electric conductivity of 72 Ω·cm.
The thermal conductivity of the composite is 159 W·m-1·K-1 with 18vol % Mo content and is 157.8 W·m-1·K-1 with 20vol% content according to the formula (1).And the thermal conductivity of the former is slightly higher than the latter.
