nowadays distillation is recognized as one of the economical and the most trustable separation methods in chemical, petroleum, gas and petrochemical industries. it is almost used as a first and the most applicable choice in separation methods. in this article the effect of inlet downcomer on the hydrodynamics of industrial sieve tray has been elaborated. the study was carried out by using a 3-d...
The computational fluid dynamics software, CFX5.5 is employed to determine dispersions of emissions from vehicles traversing the streets. Information on the layouts and heights of buildings in the selected area is contained in a digitized map layer of buildings. The Geographic Information System software, ArcView 3.2a, with its programming facility, Avenue, has been used to extract the coordina...
A new composite poly(caprolactone) (PCL) and poly(acrylic acid) (PAA) (PCL:PAA 1:5) scaffold was synthesized via dispersion of PCL particles into a PAA network. Silica microspheres (Si) (2–12 μm) were then prepared by a lyophilized micro-emulsion/sol-gel (Emugel) system using varying weight ratios. The model drug ciprofloxacin (CFX) was used for in situ incorporation into the scaffold. The phys...
An accurate description of the fluid flow and heat transfer within a Pressurized Water Reactor (PWR), for the safety analysis and reactor performance is always desirable. In this paper a mathematical model of the fundamental physical phenomena which are associated to a typical PWR is presented. The mathematical model governs the fluid dynamics in the reactor. Using commercial software CFX, a co...
This paper presents the coupled code system of PROTEUS-NODAL and SAM developed for multiphysics simulation molten salt reactors (MSRs). The coupling was made under MOOSE framework by developing a wrapper master application that controls neutronics thermal-fluidic calculations. verified validated using Molten Salt Fast Reactor (MSFR) benchmark problem available experimental data Experiments (MSR...
Abstract In this new technological world, CNC and manual turning operations engage in a significant role different types of designing manufacturing industries. Before initiating the processes, analysis is crucial part process. This study involves modelling machining process cylindrical AA6082-T6 workpiece with Tungsten Carbide tip tool. A 3D model first modelled on CATIA V5 then carried Ansys R...
Use the Spur dike as one of the easiest ways to protect the costal of the river has always been of interest to River engineers.The aim of this study was numerical investigate, the effect of distance and angle of the spur dikes parameters on the pattern of distribution of average velocity and the location of maximum velocity position at a mild 90 degree bend. For this purpose used ANSYS CFX so...
Influence of insertion of holes in the middle of obstacles on the flow around a surface-mounted cube
The aim of our study is to analyze the impact of insertion holes in the middle of obstacles on the flow around a surface-mounted cube, In order to do this; we studied four configurations of obstacles in a channel with a Reynods number based on obstacle height ReH = 40000. The hexahedral structured meshes were used to solve the fluid dynamics equations .The finite volume method are employed to s...
This research aims to simulate a gravity flow fractionation—the process to fractionate erythrocytes through gravitational field using ANSYS simulation software. A particular microfluidic channel was designed as a separation device. The gravitational equilibrium conditions of the erythrocytes and gravitational field as the parameters were chosen, then deriving the erythrocytes’ path through nume...
the developing turbulent flow in an open channel is a complex three-dimensional flow influenced by the secondary currents and free surface effects and is, therefore, not amenable to analytical solution. this paper aims to study the impact of three key hydraulic parameters (relative roughness, the froude number and the reynolds number) on the establishment length using computational fluid dynami...
