TURBULENT COMPRESSIBLE AXISYMMETRIC FLOWS COMPUTATION WITH THE K-EPSILON MODEL [PDF]
A new technique is proposed to compute axisymmetric flows using existing 2D Navier-Stokes conservative solvers. Turbulence modelling is done with a k - ∊ model for high Reynolds number regions and a k - e one-equation model for near-wall regions. Moreover, a new robust algorithm for the turbulent equations is presented. A hypersonic boundary layer on a

: The modelling of turbulence for IC engine applications is quite a challenging task. Large Eddy Simulation (LES) is the best approach to model the turbulence as the flow is three dimensional, chaotic, transient, diffusive, dissipative and intermittent ...

INFLUENCE OF DIFFERENT WIND ANGLES ON PEDESTRIAN WIND COMFORT IN 3D SPACE [PDF]
Wind can impact pedestrian comfort. This comfort can be observed by integrating a 3D city model into the study area. However, little research has been done on the influence of different wind angles on pedestrian wind comfort and rarely on implementing 3D

Modelling the dynamics of turbulent floods [PDF]
Consider the dynamics of turbulent flow in rivers, estuaries and floods. Based on the widely used k-epsilon model for turbulence, we use the techniques of centre manifold theory to derive dynamical models for the evolution of the water depth and of ...
