dense medium cyclone is a high capacity device that is widely used in coal preparation. it is simple in design but the swirling turbulent flow, the presence of medium and coal with different density and size fraction and the presence of the air-core make the flow pattern in dmcs complex. in this article the flow pattern simulation of dmc is performed with computational fluid dynamics and fluent...

Xanthan gum (XG) is widely used in cosmetic and pharmaceutic products (creams, pastes) oil industry (drilling fluids) as a stabilizing and/or thickening agent. In literature, its rheological behavior mainly presented that of shear-thinning or yield stress fluid. Here, order to clarify this behavior, we study detail the flow characteristics during continued under given conditions (i.e., controll...

Commonly used methods to predict streamflow at ungauged watersheds implicitly predict streamflow magnitude and temporal sequence concurrently. An alternative approach that has not been fully explored is the conceptualization of streamflow as a composite of two separable components of magnitude and sequence, where each component is estimated separately and then combined. Magnitude is modeled usi...

The characterization of respiratory air flow patterns is a subject of continuous interest. The pattern of the air flow curve is an individual characteristic which remains constant over long periods of time. Basically two different approaches have been proposed to determine the individual parameters of the respiratory flow, namely the graphical characterization, which originated from visual indi...

A novel approach for the computation of optical flow based on an L (1) type minimization is presented. It is shown that the approach has inherent advantages since it does not smooth the flow-velocity across the edges and hence preserves edge information. A numerical approach based on computation of evolving curves is proposed for computing the optical flow field. Computations are carried out on...
