The point of this case is to display the good behaviour of PHOENICS with fully 3D flows. Since the 3D phenomena take place downstream of the bend, a length of 8 diameters is considered. The upstream length is only 2 diameters since the slight influence of the curved duct in the inlet region. ENDDIS DISPLAY It is possible to redefine the number of cells in each direction. The 2D geometry can be changed in the following aspects: - the Radius Rc. - the angle Angu of the curvature. - the lengths of the upstream and downstream regions. ext2=8 D <--------------> * * * * * * * * * Rc <-*---|O * * * <-- U=1.29 m/s <--> ext1=2 D Rc stands for the inner radius to the centre of the duct: Rc/D = 3.375 ENDDIS DISPLAY Data (default): ---- Diameter: D=0.0445 m Curved duct curvature radius: Rc=3.375*D = 0.1501 m Inlet velocity : U= 1.29 m/s Fluid Nature : Water Kinematic viscosity: Enul= 1.E-6 m2/s Reynolds Number: Re= U*D/Enul= 57.4E3 Physical models: ---------------- Turbulence Model : K-Epsilon ENDDIS ************************************************************ Group 1.
