To investigate non-bonded interaction of Phenanthrene and BN nanostructure, geometric structure of Phenanthrene and B12N12 nano-ring with B3LYP method and 6-31g* basis set are optimized by using ab initio gaussian quantum chemical package. The main purpose of this study was to evaluate changes of electronic properties of aromatic compound in presences Nano ring field. Therefore reactivity and s...

The existing experimental technology cannot accurately and quantitatively measure the flow field structure wall boundary layer displacement effect in axial pump. Based on SST k-ω turbulence model, a three-dimensional unsteady numerical simulation of whole an pump was presented at designed operating point to overcome weakness traditional measurement methods measuring inlet studied result compare...

extended abstract 1. introduction the bond between urban and rural areas, the result of their mutual needs in a spatial system, is the basis of urban-rural continuity. one of such bonds is the transfer of agricultural goods from villages to urban market. the structure of production and the flow of agricultural products to urban market could be affected by factors such as access to natural resou...

The role of turbulence in current generation and self-excitation of magnetic fields has been studied in the geometry of a mechanically driven, spherical dynamo experiment, using a three-dimensional numerical computation. A simple impeller model drives a flow that can generate a growing magnetic field, depending on the magnetic Reynolds number Rm=micro0sigmaVa and the fluid Reynolds number Re=Va...

The evolution of blood flow patterns (vortical flow features in particular) and their interactions with cardiovascular structure is important in the study of cardiovascular function. The winding index method is widely used for vortex detection and has shown to be very sensitive to noise. We propose a novel technique for the detection of vortical flow features that consists of three main compone...
