despite the different criticisms on contrastive analysis it has been proved that the results of it(when processed) can be useful in a tefl environment, specially at the level of phonology.this study is an attempt to compare and contrast the sound systems of kurdish and english for pedagogical aims.the consonants,vowels,stress and intonation of the two languages are described by the same model...
in this paper, the turbulent air droplet flow inside a single passage of a curved type vane separator has been studied numerically. the simulation is based on the eulerian - lagrangian method. for turbulent air flow calculations, a computer code was developed to solve the reynolds averaged navier stokes (rans) equations together with the equations of reynolds stress transport model (rstm) on co...

A physical model of gabion overflow dams was studied to determine the velocity profile and Reynolds shear stress. Physical tests were done under two different conditions of dam crest, overflow dams with impermeable and with permeable crests. Instantaneous velocity components over dam crest were measured by an ADV (Acoustic Doppler Velocimeter) instrument. This instrument is capable of measuring...
A novel constrained formulation for the dynamic subgrid-scale model for large eddy simulation (LES) is proposed. It is employed as a dynamic wall model when the constraint is imposed in the near-wall region of wall-bounded flows. An externally prescribed Reynolds stress is used as the constraint. However, unlike conventional zonal approaches, Reynolds stress is not imposed as the solution, but ...

This paper presents a way of modelling turbulence in multiphase flows within the context of the Reynolds-Stress Model. The model has been implemented in the general-purpose unstructured finite volume code Fluent V6. Two multiphase turbulence approaches were considered: mixture and dispersed models. The mixture model solves the Reynolds-stress transport equations on the mixture level only. The d...
