    Evaluation of cyclone geometry and its influence on performance parameters by computational fluid dynamics (CFD) W. P ... Smagorinsky model can be thought of as combining the Reynolds averaging assumptions given by L ij + C ij = 0 with a mixing length-based eddy viscosity model for the Reynolds SGS tensor.

  • 'Moving Bed Biofilm Reactors: Evaluation of Geometry ...

    Finally, the influence of surface chemistry on biofilm attachment and performance was tested by facilitating biofilm growth on freely floating nylon and high-density polyethylene. Results indicate that organisms grown on more protected, sheltered carrier media respond to changes in mixing more rapidly than those on open and exposed media design.

  • Numerical Investigation of the Influence of Specific ...

    All numerical investigations presented in this paper were carried out using a model geometry. No experimental results were available for this geometry. The validation of the code concerning film cooling mixing was presented in [15], [16], [17] and [18] (Vogel, 1994–1996).

  • Large eddy simulation of the variable density mixing layer ...

    Temporal mixing layer DNS and LES studies have shown that the imposed initial conditions can substantially affect both the mean flow statistics, and the internal geometry of the coherent structures (Comte et al 1992, Rogers and Moser 1994, Balaras et al 2001). In spatially-developing mixing layer simulations, the specification of the inflow ...

  • Why Structural Fiber is the Smart Choice for Thin Concrete ...

    Therefore, consideration of fiber geometry and stiffness when choosing fibers for concrete overlays often becomes an economic choice, where the designer must balance cost, workability, and performance. Regarding the influence of the material on the residual strength, steel fibers often outperformed synthetic fibers by a significant margin.
