.... Finally, a computational fluid dynamics (CFD) analysis with cfx was performed using single- and two-phase flow techniques. Fig. 3 Typical sizes for PCA025. Outer diameter D 2  = 33.9 mm, inner diameter D 1  = 25.4 mm, pitch p  = 5.2 mm, wall thickness t  = 0.4 mm, and ridge depth r  = 4.25...

... density and pressure fluctuations are found. Therewith, the builtup Rayleigh-scattering system enables investigations of the presumed region of indirect noise generation. 15 04 2010 06 05 2010 10 11 2010 10 11 2010 density measurement fluid dynamics nozzles optical variables...

.... The role of bend geometry and, in particular, the short and long radii, surface roughness, wall shear stress, and local turbulence, is discussed. Computational fluid dynamics calculations and plant artifact measurements for short- and long-radius bends are presented. The effect of the close proximity...

... are coupled with experimentally derived empirical equations, or time-consuming computations are used. Coupling nonequilibrium chemistry, fluid dynamic, and initial and boundary condition equations results in large sets of numerically stiff equations; and their time integration demands enormous computational...
