Initially, G. the simulation was compared with in-house experimental results which indicated discrepancies in turbulence intensity data obtained between computational and experimental approach.
This was further analyzed by performing the single jet analysis using other turbulence models and comparing the results. III. GEOMETRY AND MESH GENERATION.

Introduction Recent studies of turbulent shear flows have shown that many of their important kinematical and dynamical properties can be more clearly understood by describing.
It appears that turbulence was already recognized as a distinct ﬂuid behavior by at least years ago (and there are even purported references to turbulence in the Old Testament). The following ﬁgure is a rendition of one found in a sketch book of da Vinci, along with a remarkably modern description.

Comparisons between the mean inlet pressure (P 1) for stenosis percentages of 30%, 50%, 70%, and 80% are given in Figure can be seen, up to 70% stenosis, there is a very good consistency between experimental results  and the laminar flow assumption which suggests that, up to 70% stenosis, the flow is ng from 70% to 80%, the difference Cited by: We propose a new length scale as a basis for the modelling of subfilter motions in large-eddy simulations (LES) of turbulent flow.
Rather than associating the model length scale with the computational grid, we put forward an approximation of the integral length scale to achieve a non-uniform flow coarsening through spatial filtering that reflects the local, instantaneous turbulence.
