Silting in river is a dynamic process, so it needs to regular desilting. At present, underwater siltation monitoring still its early days and based on experience. This paper puts forward the criterion of discrimination, which flood discharge section decreased by 20%. It used method steady uniform flow open rectangular trapezoidal channel for calculation. The results show that reference values d...

We study diffusiophoretic exclusion zone (EZ) formation in rectangular channel flow, driven by CO 2 dissolution from one side wall. By using a similarity transform and considering the flow structure, we obtain relation between EZ wall shear rate.

A channel is a rectangular region of VLSI layout, between pair of adjacent blocks and is used for interconnecting the nets of signal, clock, and ground. With increased scaling of the chips, the coupling capacitance between the interconnect lines becomes predominant. This capacitance along with the increased interconnect lengths, clock frequencies and reduced supply voltages lead to noise in net...

We present a new semi-discrete central scheme for one-dimensional shallow water flows along channels with non-uniform rectangular cross sections and bottom topography. The scheme preserves the positivity of the water height, and it is preserves steady-states of rest (i.e., it is wellbalanced). Along with a detailed description of the scheme, numerous numerical examples are presented for unstead...

In this paper the laminar flow in the rectangular channel bends is simulated using numerical techniques. The turning angle of the channel bend and the area ratio of the channel cross-section are two important parameters to be examined. For flow simulation, the body fitted 3-D continuity and momentum equations are used and a body fitted general purpose code is developed. The existing results of ...

this study seeks to examine how a company can select the best intermediary for its marketing channels with minimum of criteria and time. a theoretical framework is proposed based on the most important tasks of intermediary and the criteria to measure them. there are four basic tasks and thirty criteria in three independent levels. subsequently, an exploratory case study in iranian food industry...
