iranian islamic gardens like almost every cultures, represent beauty and happiness and improve the public perception. it has also special geometry with philosophical concept related to islam’s doctrine that is the focus of this research. following quran’s contents, paradise is a beautiful sophisticated garden that something flows under its trees. so the comparison between the somatic geometry o...

In the theory of traffic flows the main characteristics are: intensity, speed, and density.  They make it possible to use hydrodynamic models. In connection with the development of modern highways and road networks, traffic flows behavior is becoming more and more complex and diverse. In particular, the B.Kerner studies have shown that the laminar solution of hydrodynamic models is poorly corre...

We give a symbolic construction of Shunji Ito’s “transversal flow for a subshift of finite type” [I], along the lines of Vershik’s construction of an adic transformation. We then show how these flows arise naturally in the symbolic coding of horocycle flows on non-compact hyperbolic surfaces with finite area.

Multiphase flows exist widely in daily life and many industrial processes, such as soap bubbles, rain drops, internal combustion engines, thermal spray coating, and ink-jet printing, et al. In the numerical study of multiphase flows with clear interfaces, it is extremely important to accurately track the interfaces. Many numerical methods have been developed to treat the interface, including Le...

The Root Zone Water Quality Model (RZWQM, V 3.25) was used to simulate the effect of swine manure applications on nitrate-nitrogen (NO3-N) concentrations in subsurface drain water from continuous corn for Iowa soils. Measured values of subsurface drain flow, NO3-N concentrations in drainage water, and residual NO3-N in the soil profile from three chisel plow plots were available for the growing...

Arterial stenosis, for example Atherosclerosis, is one of the most serious forms of arterial disease in the formation of which hemodynamic factors play a significant role. In the present study, a 3-D rigid carotid artery with axisymmetric stenosis with 75% reduction in cross-sectional area is considered. Laminar blood flow is assumed to have both Newtonian and non-Newtonian behavior (generalize...

A numerical study of 3D electrokinetic flows through micromixers was performed. The micromixers considered here consisted of heterogeneous rectangular microchannels with prescribed patterns of zeta-potential at their walls. Numerical simulation of electroosmotic flows within heterogeneous channels requires solution of the Navier-Stokes, Ernest-Plank and species concentration equations. It is kn...
