Modeling complex flow structures and drag around a submerged plant of varied posture

Numerical Simulation of Flow Pattern around the Bridge Pier with Submerged Vanes

Bridges are very important for establishing communication paths. For this reason, it is important to control scour around bridge piers. Several methods have been proposed for scour control. One of the most useful methods is the use of submerged vanes. In the other hand, laboratory circumstances force many considered effective factors to be skipped in the scour phenomenon. In this situation, the...

Spatially Varied Flow Profiles in a V-Shaped Side-Channel

Drag coefficient and strouhal number analysis of a rectangular probe in a two-phase cross flow

In some case of laboratory and industrial applications, various kind of measurement instruments must be placed in a conduit, in which multiphase fluid flows. Vortex shedding for any immersed body in flow field is created with a frequency, which according to flow conditions such as flow rates, geometry of body, etc. may be constant or variable. Failure may happen, if this frequency is close to o...

Yield drag in a two-dimensional foam flow around a circular obstacle: effect of liquid fraction.

We study the two-dimensional flow of foams around a circular obstacle within a long channel. In experiments, we confine the foam between liquid and glass surfaces. In simulations, we use a deterministic software, the Surface Evolver, for bubble details and a stochastic one, the extended Potts model, for statistics. We adopt a coherent definition of liquid fraction for all studied systems. We va...

A comprehensive review on modeling of nanocomposite materials and structures

This work presents a historical review of the researches procured by various scientists and engineers dealing with the nanocomposite materials and continuous systems manufactured from such materials. Nanocomposites are advanced type of well-known composite materials which have been reinforced with nanosize reinforcing fibers and/or particles. Such materials can be better suit for the industrial...
