Corresponding Author: Ling Zhou Research Center of Fluid Machinery Engineering and Technology, Jiangsu University, Zhenjiang, China Email: [email protected] Abstract: The Filter-Based Model (FBM), which was built into CFX through CFX Expression Language (CEL) and a homogeneous cavitation model were employed to simulate cavitating flow around a 2D Clark-y hydrofoil. The effect of a maximum de...
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...
purpose: in recent years high explosive bomb attacks have been increasingly directed against civil structures by various terrorist organizations. this paper describes a numerical method for assessing the interaction of high explosive air blast within the complex geometrical type of a congested urban environment. materials and methods: the first step in predicting blast effects on a targ...
مهم ترین هدف این مقاله، تصحیح هیل چارت نیروگاه مارون است. به این منظور از روش های عددی به کمک نرم افزار ansys cfx برای شبیه سازی جریان در اجزای توربین استفاده شده است؛ که شامل موارد زیر است: محفظه حلزونی، پره های ثابت، پره های متحرک، رانر و درافت تیوب. هندسه چرخ به وسیله cmm و هندسه سایر اجزا به وسیله نقشه های موجود، به کمک نرم افزار catia رسم شده است. شبیه سازی جریان، برای دبی های مختلف ورودی،...
Reaction processes of fluorine ~F! atoms in high-density carbon–tetrafluoride (CF4) plasmas were investigated using vacuum ultraviolet absorption spectroscopy. A scaling law nF}(nenCF4) 0.5– 0.7 was found experimentally, where nF is the F atom density and ne and nCF4 stand for the electron and parent gas (CF4) densities, respectively. The lifetime measurement in the afterglow showed that the de...
An optimal installation of a compound parabolic concentrator (CCPC) into a scalable solar thermoelectrics and photovoltaics system is desirable by applying analytical tools to improve the optical and thermal performance of a CCPC with a solar cell. In this paper, the optical and thermal performances of an isolated CCPC with solar cell are investigated by employing commercial software ‘ANSYS CFX...
The advanced validation of a CFD code for containment applications requires the investigation of water steam in the different flow types like jets or buoyant plumes. This paper addresses therefore the simulation of two “HYJET” experiments from the former Battelle Model Containment by CFX. These experiments involve jet releases into the multi-compartment geometry of the test facility accompanied...
Due to low intra- and interrater reliability, perceptual voice evaluation should be supported by objective, automatic methods. In this study, text-based, computer-aided prosodic analysis and measurements of connected speech were combined in order to model perceptual evaluation of the German Roughness-Breathiness-Hoarseness (RBH) scheme. 58 connected speech samples (43 women and 15 men; 48.7 ± 1...
در پایان نامه ارائه شده، جریان خون در یک انشعاب کرونری با یک شاخه غیر همسطح به صورت عددی مدل سازی گشته است. جریان به صورت پالسی، سه بعدی و آرام و دیواره رگ به صورت الاستیک در نظر گرفته شده است. ابتدا جریان در یک انشعاب با زاویه ?90 به صورت نیوتنی و غیر نیوتنی بررسی شده و نتایج با هم مقایسه گردیده است. سپس جریان غیر نیوتنی خون در انشعابات با زاویه ?60 و ?75 مورد مطالعه قرار گرفته و اثر زاویه انش...
