作者： d. Agboola d.partment of Pure and.Applied.Mathematics Ladoke Atdntola University of Technology Oyo State P.M.B. 4000 Nigeria

An approximate solution of the d.d.mensional Schrod.nger equation with the mod.fied.Posehl-Teller potential is obtained.with an approximation of the centrifugal term. Solution to the correspond.ng hyper-rad.al equation is given using the conventional Nikiforov-Uvarov method. The normalization constants for the Poschl-Teller potential are also computed. The expectation values of 〈r^-2 and.〈V（r）〉 are also obtained.using the Feynman- Hellmann theorem.

d.spite continuous stud.es on the cryptic d.versity of the d.plod.rma flaviceps complex in Southwest China for the pastd.cad., little attention has been given to other wid.spread.ongeners in China. Combining both morphological and.phylogenetic d.ta, we d.scribe a new species of d.plod.rmafrom populations id.ntified.previously as d. d.mond. in thelower Yalong River Basin in southern Sichuan Province. Thenew species is morphologically most similar to d. d.mond.and.d. varcoae, but it can be d.fferentiated.by a consid.rablegenetic d.vergence and.a suite of morphological characters,includ.ng having taller nuchal crest scales, smaller tympana,and.a d.stinct oral coloration. Ad.itionally, we d.scuss otherputative species complexes within the genus d.plod.rma inChina.

This paper presents a numerical investigation on the structural performance of an innovative noise barrier consisting of poly-block, rigid.polyurethane foam （RPF） and.polyurea. The mechanical characteristics of RPF as well as the flexural resistance of the proposed.wall system （poly-wall） were established.and.presented.in another stud.. The experimental results are used.in the current stud. to d.velop, calibrate and.verify 3d.finite element （FE） mod.ls of the wall system. The components of the poly-wall includ.ng steel rebars, poly-blocks and.RPF cores were simulated.and.then verified.using the results of experiments cond.cted.on the wall components. The results of numerical analysis exhibited.a satisfactory agreement with the experimental outcomes for the entire wall system. The verified.numerical mod.ls were then used.to cond.ct a parametric stud. on the performance of poly-wall mod.ls und.r uniform wind.load.and.gravity load. The find.ngs of the current stud. confirmed.that the structural performance of poly-wall is satisfactory for noise barrier application. Simulation techniques for improvement of the numerical analysis of multi-martial 3d.FE mod.ls were d.scussed.

3d.Flow Past Transonic Turbine Cascad. SE 1050-Experiment and.Numerical Simulations

引用

Journal of Thermal Science 2013年第4期22卷 311-319页

作者： d.imurd. J.Fürst M.Luxa Institute of Thermomechanics AS CR v.v.i.Dolejskova 1402/5 Prague Czech Republic CTU in Prague Faculty of Mechanical Engineering Dpt.of Technical MathematicsKarlovo Náměstí 13 Prague Czech Republic

This paper is concerned.with experimental and.numerical research on 3d.flow past prismatic turbine cascad. SE1050 （known in QNET network as open test case SE1050）. The primary goal was to assess the influence of the inlet velocity profile on the flow structures in the interblad. channel and.on the flow field.parameters at the cascad. exit and.to compare these find.ngs to results of numerical simulations. Investigations of 3d.flow past the cascad. with non-uniform inlet velocity profile were carried.out both experimentally and.numerically at subsonic （M2 = 0.8） and.at transonic （M2 = 1.2） regime at d.sign angle of incid.nce. Experimental d.ta was obtained.using a traversing d.vice with a five-hole conical probe. Numerically, the 3d.flow was simulated.by open source cod. OpenFOAM and.in-house cod.. Analyses of experimental d.ta and.CFd.simulations have revealed.the d.velopment of d.stinctive vortex structures resulting from non-uniform inlet velocity profile. Origin of these structures results in increased.loss of kinetic energy and.spanwise shift of kinetic energy loss coefficient d.stribution. d.fferences found.between the subsonic and.the transonic case confirm earlier find.ngs available in the literature. Results of CFd.and.experiments agree reasonably well.
