13D radiative convective flow of ZnO-SAE50nano-lubricant in presence of varying magnetic field and heterogeneous reactions显示文摘A numerical simulation is presented to investigate the effect of an exponentially varying magnetic field on three dimensional flow of Zinc Oxide-Society of Automotive Engineers 50 nanolubricant(ZnO-SAE50nano-lubricant)past a stretching sheet.Subsequently the impact of homogenous and heterogeneous reactions on the flow of nanolubricant concerned has also taken into account.The study has been strengthened by introducing the convection mechanism and the effect of thermal radiation.Similarity transformations are employed to transform the set of partial governing equations into the set of ordinary differential equations.The suitable boundary conditions are used to obtain the numerical solution.The numerical results are simulated using Matlab bvp4c solver and validated with the existing results.The flow characteristics,thermal characteristics,nanoparticle concentration and some non-dimensional numbers are computed under the influence of the pertinent parameters.The valuable outcome of the current study is that augmented magnetic field strength is the root cause of diminishing axial as well as transverse velocities and growing trend of fluid temperature.Also,the coeffi-cients of homogenous and heterogeneous reactions are boons for ascending concentration boundary layer.M.K.Nayak J.Prakash D.Tripathi V.S.Pandey 2019Propulsion and Power Research2019,8,4:1
2Mathematical modelling on phase based transmissibility of Coronavirus显示文摘Mathematical and epidemiological simulation plays a pivotal role in predicting,anticipating,and controlling present and future epidemics.To better understand and model the dynamics of a specific infection,researchers need to consider the influence of many variables ranging from micro-hostepathogen interactions to host-to-host encounters,and the prevailing cultural,social,economic,and local customs worldwide.As reported by the WHO,a novel corona virus(COVID-19)is identified as the etiological virus through Wuhan pneumonia for unknown etiology with Chinese administration on Jan 7,2020.This virus is designated as an unsympathetic SARS-Cov-2 by International Commission for Taxonomy of Viruses on Feb 11,2020.The main aim is to enlarge a phase based mathematical modelling to specify the transferability of this disease.It is developed Reservoir-individuals spreading set of connections modelling for imitating the prospective broadcast as of the infectivity foundation in the direction of the person infectivity.In view of the fact that,the Reservoir has set of connections to rigid to see the sights obviously as well as communal anxieties are concentrating on top of the spreading starting reservoir to individuals.The subsequent generation matrix methodology is endorsed towards compute the fundamental reproduction number(R0)through the RP modelling to measure the transferability by the COVID-19.The values of R0 are estimated from reservoir to human being as well as starting individual to individual,that is to say,the accepted quantity of less important diseases this consequence from presenting a solitary contaminated personality addicted to differently susceptible inhabitants.The present model demonstrated that the spreading of COVID-19 is superior to the Middle-East pulmonary infirmity during the Middle-East nationals,analogous to harsh sensitive pulmonary infirmity,but inferior than Middle-East pulmonary infirmity within the Republic of Korea.It can also extend this study to some other countries,including Saudi Arabia,Italy,and Germany etc.The COVID-19 pandemic has become the leading societal concern.The pandemic has shown that the public health concern is not only a medical problem,but also affects society as a whole;so,it has also become the leading scientific concern.M.Veera Krishna J.Prakash 2020Infectious Disease Modelling2020,5,1:0
3细晶碳化钨基硬质合金的应用显示文摘超细硬质合金,因其具有最佳的硬度与韧性结合的性能,市场占有率达到目前整个硬质合金消耗总量的10%~15%.其主要用作机加工木材和木质材料,塑料、复合材料,黑色与有色金属加工部件,也可用于罐(盒)、高压穿孔等无屑加工和磨损部件材科等。这种特制超细硬质合金不仅为硬质合金开辟了新的应用领域,而且不大大提高了其耐磨性。Leo J.Prakash 钟培全 1996中国钨业1996,11,3:0
