Modelling of turbulent swirling flows [PDF]
, 2004 This thesis investigates the predictability of non-reacting and reacting anistropic turbulent, swirling flows using popular turbulence models with a robust numrical procedure. The performance of these turbulence models is assessed and compared against

Parametric forcing approach to rough-wall turbulent channel flow [PDF]
, 2012 The effects of rough surfaces on turbulent channel flow are modelled by an extra force term in the Navier–Stokes equations. This force term contains two parameters, related to the density and the height of the roughness elements, and a shape function ...

Unified Friction Formulation from Laminar to Fully Rough Turbulent Flow
Applied Sciences, 2018 This paper provides a new unified formula for Newtonian fluids valid for all pipe flow regimes from laminar to fully rough turbulent flow. This includes laminar flow; the unstable sharp jump from laminar to turbulent flow; and all types of turbulent ...

The unsteady turbulent flows structure study present status [PDF]
INCAS Bulletin, 2019 The processes of heat transfer and hydraulic plays a very important role in the design and prototyping of aerospace technology. In most cases this technique works under significant unsteady conditions. Steady approach for unsteady processes leads to high
