| 1 | Liutex core line and POD analysis on hairpin vortex formation in natural flow transition显示文摘In this study,the new method of the vortex core line based on Liutex definition,also known as Liutex core line,is applied to support the hypothesis that the vortex ring is not a part of theΛ-vortex and the formation of the ring-like vortex is formed separately from theΛ-vortex.The proper orthogonal decomposition(POD)is also applied to analyze the Kelvin-VHelmholtz(K-H)instability happening in hairpin ring areas of the flow transition on the flat plate to understand the mechanism of the ring-like vortex formation.The new vortex identification method named modified Liutex-Omega method is efficiently used to visualize and observe the shapes of vortex structures in 3-D.The streamwise vortex structure characteristics can be found in POD mode one as the mean flow.The other POD modes are in stremwise and spanwise structures and have the fluctuation motions,which are induced by K-H instability.Moreover,the result shows that POD modes are in pairs and share the same characteristics such as amplitudes,mode shapes,and time evolutions.The vortex core and POD results confirm that theΛ-vortex is not self-deformed to a hairpin vortex,but the hairpin vortex is formed by the K-H instability during the development of Lambda vortex to hairpin vortex in the boundary layer flow transition. | Sita Charkrit Pushpa Shrestha Chaoqun Liu | 2020 | Journal of Hydrodynamics2020，32，6： | 4 |
| 2 | Magnetic separation studies for a low grade siliceous iron ore sample显示文摘Investigations were carried out, on a low grade siliceous iron ore sample by magnetic separation, to establish its amenability for physical beneficiation. Mineralogical studies revealed that the sample consists of magnetite, hematite and goethite as major opaque oxide minerals where as silicates as well as carbonates form the gangue minerals in the sample. Processes involving combination of classification, dry magnetic separation and wet magnetic separation were carried out to upgrade the low grade siliceous iron ore sample to make it suitable as a marketable product. The sample was first ground and each closed size sieve fractions were subjected to dry magnetic separation and it was observed that limited upgradation is possible. The ground sample was subjected to different finer sizes and separated by wet low intensity magnetic separator. It was possible to obtain a magnetic concentrate of 67% Fe by recovering 90% of iron values at below 200 lm size. | Dwari Ranjan Kumar Rao Danda Srinivas Reddy Palli Sita Ram | 2013 | International Journal of Mining Science and Technology2013，23，1： | 3 |
| 3 | Characterization of dolochar wastes generated by the sponge iron industry显示文摘Solid wastes generated by the metallurgical industry contribute significantly towards the enhancement of environmental pollution. The handling, utilization, and safe disposal of these solid wastes are major concerns for the world. Dolochar is such a solid waste generated by the sponge iron industry. Investigations were carried out on the physical, mineralogical, and chemical characteristics for the efficient utilization of dolochar. The detailed studies on physico-chemical properties and petrography were carried out by optical microscopy, X-ray diffraction (XRD), and scanning electron microscopy (SEM). Characterization studies revealed that the dolochar consists of quartz (free as well as locked), free lime, Fe particles, and Ca or Mg and/or Ca+Mg+Fe oxide phases. The washability data of-300 μm dolochar samples indicated that clean coal with 41wt% ash at 18% yield can be produced from dolochar with 78wt% ash. The studies further suggested that the liberation of the dolochar is hard to achieve for clear separation. The dolochar is observed to have high ash fusion temperature and the unburned carbon can be best utilized for power generation. | Ranjan Kumar Dwari Danda Srinivas Rao Akhila Kumar Swar Palli Sita Ram Reddy Barada Kanta Mishra | 2012 | International Journal of Minerals,Metallurgy and Materials2012，19，11： | 2 |

| 5 | Direct injection HILIC-MS/MS analysis of darunavir in rat plasma applying supported liquid extraction显示文摘A novel bioanalytical method was developed and validated for the quantitative determination of darunavir(DRV) in rat plasma by employing hydrophilic interaction chromatography and tandem mass spectrometry(HILIC-MS/MS) with supported liquid extraction(SLE).lrbesartan(IRB) was used as an internal standard(IS).The analyte in rat plasma(200 μL) was isolated through SLE using ethyl acetate as the eluting solvent.The chromatographic separation was achieved on Luna-HILIC(250 mm × 4.6 mm,5 μm)column with a mobile phase of 0.1% of formic acid in water:acetonitrile(5:95,v/v),at a constant flow rate of 1.0mL/min.The MS/MS ion transitions for DRV(548.1→392.0) and IS(429.2→207.1) were monitored on an ion trap mass spectrometer,operating in the multiple reaction monitoring(MRM) mode.The lower limit of quantitation(LLOQ) was 0.2 ng/mL and quantitation range was 0.2-5000 ng/mL.The method was validated for its selectivity,sensitivity,carryover,linearity,precision,accuracy,recovery,matrix effect and stability.The method was successfully applied to pharmacokinetic study in rats. | Bokka Ramesh Nemali Manjula Sistla Ramakrishna Potturi Sita Devi | 2015 | Journal of Pharmaceutical Analysis2015，5，1： | 2 |
