The additional term b | u x | 2, reminiscent of the Kuramoto-Sivashinsky equation, which arises in the study of various pattern formation phenomena involving some kind of phase turbulence or phase transition (see [6 8]), breaks the symmetry u → − u.
The additional term (bvert nabla uvert ^{2}) arises in the study of various pattern formation phenomena involving some kind of phase turbulence or phase transition that breaks the symmetry (urightarrow-u).
The free-surface-elevation fluctuations and velocity components were measured simultaneously with two sets of cameras to examine phase-averaged parameters of turbulence.
Using phase Doppler anemometry the scale of turbulence and the spray dilution by air entrainment are investigated during nanoparticle synthesis by flame spray pyrolysis (FSP).
An adaptive mathematical model was developed to determine the local phenomenological properties of turbulence in two phase solid particles-gas system.
The present work examines the predictive capability of two-fluid CFD model based on the kinetic theory of granular flow in capturing the Reynolds number (Re) dependence of fluid-phase turbulence modulations in dilute-phase turbulent liquid particle flows.
Principles of designing a phase function to achieve the desirable distribution of turbulence scales, and two-point correlations, are outlined by considering the example of Uniform Isotropic Turbulence.
Within this approach, the accurate prediction of the fluid dynamics depends on the correct modeling of (a) the momentum exchange between the phases, (b) the effects of the dispersed phase on the turbulence of the continuous phase, and (c) the bubble coalescence and break-up phenomena.
The resulting modification of carrier phase turbulence, estimated according to current computational models, was evaluated.
With the models of gas phase turbulence, heat and mass transfer, and chemical reactions being considered, a comprehensive 3D model for FGD process (Flue Gas Desulfurization) is established, and several operation conditions are simulated by the model.
