| 1 | 黑龙港流域夏玉米生育期降水、需水和干旱时空分布特征显示文摘黑龙港流域地下水超采导致水分极度匮乏,提高降水利用效率成为该区夏玉米生产的关键。该文利用黑龙港流域18个地面气象观测站1966-2015年逐日气象数据,对玉米全生育期及各生育阶段的有效降水量、需水量、作物水分亏缺指数、干旱发生频率的时空分布特征等进行了分析。结果表明,夏玉米全生育期有效降水量292.89~361.56 mm,呈'东北高、西南低'的趋势;需水量362.82~444.04 mm,呈'南部高,北部低'的趋势;近50年总有效降水量和需水量均呈下降趋势,且需水量的变化与平均日照时数、平均风速呈高度正相关;全区干旱发生频率为48.30%,其中南部超33.3%,中部及北部超66.6%;黑龙港中部和北部在成粒和灌浆阶段出现干旱的几率较大,南部在成粒阶段出现干旱的几率较大。该研究为黑龙港夏玉米降水资源的高效利用提供了理论依据。 | 魏钟博 边大红 杜雄 Pushpa Raj 崔彦宏 | 2020 | 农业工程学报2020，36，9： | 8 |
| 2 | 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 |
| 3 | Case report on an infant presenting with hypoglycemia,and milky serum显示文摘A 4-month-old male baby who presented in a moribund condition with seizures was found to have hepatomegaly,hypoglycemia and milky serum.Serum triglycerides were markedly elevated(3168 mg/dL) with cholesterol being 257 mg/dL and high density lipoprotein levels were low(19 mg/dL).The possibility of glycogen storage disease type Ⅰ was considered in the diagnosis.Infants with glycogen storage disease type Ⅰ may present like sepsis.The association of hepatomegaly, hypoglycemia and abnormal lipid profile stated above should alert the physician to consider glycogen storage disease type Ⅰ in the diagnosis. | Yogesh Kumar Gupta Anushre Prasad Pushpa Kini Prashant Naik Deepti Choprra Krishnananda Prabhu | 2012 | Asian Pacific Journal of Tropical Biomedicine2012，2，4： | 3 |
| 4 | Stretching and shearing contamination analysis for Liutex and other vortex identification methods显示文摘The newly developed vortex-identification method,Liutex,has provided a new systematic description of the local fluid rotation,which includes scalar,vector,and tensor forms.However,the advantages of Liutex over the other widely used vortexidentification methods such as Q,Δ,λ2,andλci have not been realized.These traditional methods count on shearing and stretching as a part of vortex strength.But,in the real flow,shearing and stretching do not contribute to fluid rotation.In this paper,the decomposition of the velocity gradient tensor is conducted in the Principal Coordinate for uniqueness.Then the contamination effects of stretching and shearing of the traditional methods are investigated and compared with the Liutex method in terms of mathematical analysis and numerical calculations.The results show that the Liutex method is the only method that is not affected by either stretching or shear,as it represents only the local fluid rigid rotation.These results provide supporting evidence that Liutex is the superior method over others. | Pushpa Shrestha Charles Nottage Yifei Yu Oscar Alvarez Chaoqun Liu | 2021 | Advances in Aerodynamics2021，3，1： | 3 |
| 5 | Principal coordinates and principal velocity gradient tensor decomposition显示文摘Helmholtz velocity decomposition and Cauchy-Stokes tensor decomposition have been widely accepted as the foundation of fluid kinematics for a long time.However,there are some problems with these decompositions which cannot be ignored.Firstly,Cauchy-Stokes decomposition itself is not Galilean invariant which means under different coordinates,the stretching(compression)and deformation are quite different.Another problem is that the anti-symmetric part of the velocity gradient tensor is not the proper quantity to represent fluid rotation.To show these two drawbacks,two counterexamples are given in this paper.Then“principal coordinate”and“principal decomposition”are introduced to solve the problems of Helmholtz decomposition.An easy way is given to find the Principal decomposition which has the property of Galilean invariance. | Yifei Yu Pushpa Shrestha Charles Nottage Chaoqun Liu | 2020 | Journal of Hydrodynamics2020，32，3： | 3 |
| 6 | Correlation analysis among vorticity,Q method and Liutex显示文摘Influenced by the fact that vorticity represents rotation for rigid body,people believe this idea also works for fluid flow.However,the vortex predictions by vorticity do not match experimental results,which drove scientists to look for more appropriate methods to identify vortex.All vortex identification methods can be categorized into three generations.The vorticity-based method is classified as the first generation.Methods relying on eigenvalues of velocity gradient tensor are considered as the second generation.People still believe vorticity is vortex since vorticity theory looks correct in mathematics,but all other methods are only scalars and unable to indicate the swirl direction.Recently,a new vortex identification method called Liutex is innovated.It is regarded as the third-generation method,not only overcoming all previous methods’drawbacks but also having a clear physical meaning.The direction of Liutex represents the swirl axis of rotation,and its strength is equal to twice the angular speed.In this paper,we did a correlation analysis between vorticity,Q,λ_(ci),λ_(2)methods and Liutex based on a direct numerical simulation(DNS)case of boundary layer transition.The results show that the correlation between vorticity and Liutex is very small or even negative in strong shear regions,which demonstrates that using vorticity to detect vortex lacks scientific foundation and vorticity is not appropriate to represent vortex.The correlation analysis also shows that the second generation is contaminated too by shear and thus is not accurate to identify the vortex structure. | Yifei Yu Pushpa Shrestha Oscar Alvarez Charles Nottage Chaoqun Liu | 2020 | Journal of Hydrodynamics2020，32，6： | 2 |
