چکیده

Many natural phenomena involve dynamic fluids whose motion differs radically from that of rigid bodies. This paper presents a novel approach for estimating fluid motion fields. It first estimates a local flow probability distribution function at each pixel using the STAR model and the data from a spatio-temporal neighborhood. It then feeds the set of distribution functions into a global optimization framework. As a result, the optimization returns a motion field with a unique velocity vector at each pixel. Experiments with real fluid sequences show that this method can successfully estimate their motion fields.

Multi-scale Modeling of 1-D Permeability Fields

Permeability plays an important role in subsurface fluid flow studies, being one of the most important quantities for the prediction of fluid flow patterns. The estimation of permeability fields is therefore critical and necessary for the prediction of the behavior of contaminant plumes in aquifers and the production of petroleum from oil fields. In the particular case of production of petroleu...

Multivariate Jeffrey Fluid Flow past a Vertical Plate through Porous Medium

An analysis is suggested to study the impact of Hall currents in Jeffrey fluid which is chemically reactive through a porous medium limited by a semi-infinite vertical permeable plate within the existence of heat generation. An evenly distributed magnetic field turns vertically on the porous surface which absorbs the Jeffrey fluid with a changed suction velocity with time. The analytical expres...

Wave Propagation Analysis of CNT Reinforced Composite Micro-Tube Conveying Viscose Fluid in Visco-Pasternak Foundation Under 2D Multi-Physical Fields

In this research, wave propagation analysis in polymeric smart nanocomposite micro-tubes reinforced by single-walled carbon nanotubes (SWCNT) conveying fluid is studied. The surrounded elastic medium is simulated by visco-Pasternak model while the composite micro-tube undergoes electro-magneto-mechanical fields. By means of micromechanics method, the constitutive structural coefficients of nano...

Comparisons of Experimental and Simulated Velocity Fields in Membrane Module Spacers

Spacers are used in spiral wound and plate and frame membrane modules to create flow channels between adjacent membrane layers and mix fluid within the flow channel. Flow through the spacer has a significant beneficial impact on mixing and resulting mass transfer rates but is accompanied by an undesirable increase in pressure drop. Computational Fluid Dynamics (CFD) is a common tool used to eva...

Numerical simulation of flow hydrodynamic around dolphin body in viscous fluid

The biomimetic and hydrodynamic study of aquatic animals is one of the most challenging computational fluid dynamics topics in recent studies due to the complexity of body geometry and the type of flow field. The movement of the aquatic body, and particularly the tail section and the corresponding movement of fluid around the body, causes an unsteady flow and requires a comprehensive study of t...
