Opvoedkundige teorie en praktyk berus op teveel mites wat verwerp behoort te word. Die ware beginsels van leer is dat alle mense ’n natuurlike gawe en potensiaal tot leer en ’n gretige nuuskierigheid oor die wêreld het. Leer sal meer geredelik plaasvind as die leerder voel dat die vak met sy behoeftes verband hou en as hy aktief in die leerproses betrokke is. Die waardevolste les is om te leer ...

An unsteady two-dimensional numerical investigation was performed on the viscous flow passing through a multi-blade cascade. A Cartesian finite-volume approach was employed and it was linked to Van-Leer's and Roe's flux splitting schemes to evaluate inviscid flux terms. To prevent the oscillatory behavior of numerical results and to increase the accuracy, Monotonic Upstream Scheme for Conservat...

In this work, a study involving the fully coupled Euler and Navier-Stokes reactive equations is performed. These equations, in conservative finite volume contexts, employing structured spatial discretization, on condition of thermochemical non-equilibrium, are analyzed. High-order studies accomplished using Spectral method Streett, Zang, Hussaini. The high enthalpy hypersonic flows around circu...

We develop a formulation for the single-fluid/two-temperature equations for simulating two-species, compressible, non-equilibrium plasma flows. The divergence-free condition of the magnetic field is enforced via the characteristic decomposition of an extended nine-wave system. The source terms are modified appropriately to improve energy and momentum conservation accuracy. A spectral/hp element...

Die Sheffield-verpleegskool is een van die grootste in Engeland met meer as ’n 1 000 studente op 25 verskillende basiese en naregistrasie kursusse. Die klem val op die kliniese aspek en verbeterde, totale en geindividualiseerde pasiëntsorg. Onderrig in die kliniese situasie is dan ook ’n belangrike deel van die opleiding. ’n Geintegreerde benadering tot kurrikulumontwikkeling en -implementering...

Die meeste van ons leer tydens ons opleiding wat die werking en newe-effekte van m edikam ente is, maar baie min van ons word geleer hoe om m edikamente te misbruik. Dit lyk egter of dit ’n kuns is wat verskillende lede van die mediese en verpleegberoep asook die algemene publiek deur herhaalde bantering verkry. Die doel van die referaat is om voorbeelde te gee van enkele maniere waarop m edika...

Over the last ten years, robustness of schemes has raised an increasing interest among the CFD community. The objective of this article is to solve the quasi-one-dimensional compressible flow inside a “Shubin nozzle” and to investigate Bean-Warming and flux vector splitting methods for numerical solution of compressible flows. Two different conditions have been considered: first, there is a sup...

The aim of this work is to analyze a viscous flow in the axisymmetric nozzle taken into account the mesh size both in the free stream and into the boundary layer. The resolution of the NavierStokes equations is realized by using the finite volume method to determine the supersonic flow parameters at the exit of convergingdiverging nozzle. The numerical technique uses the Flux Vector Splitting ...

The present work introduces a modified scheme for the solution of compressible 2-D full Navier-Stokes equations, using Flux Vector Splitting method. As a result of this modification, numerical diffusion is reduced. The computer code which is developed based on this algorithm can be used easily and accurately to analyze complex flow fields with discontinuity in properties, in cases such as shock...
