Perspective: A Method for Uniform Reporting of Grid Refinement Studies
Tập 116 Số 3 - Trang 405-413 - 1994
Patrick J. Roache
This paper proposes the use of a Grid Convergence Index (GCI) for the uniform reporting of grid refinement studies in Computational Fluid Dynamics. The method provides an objective asymptotic approach to quantification of uncertainty of grid convergence. The basic idea is to approximately relate the results from any grid refinement test to the expected results from a grid doubling using a ...... hiện toàn bộ
Mathematical Basis and Validation of the Full Cavitation Model
Tập 124 Số 3 - Trang 617-624 - 2002
A.K. Singhal, M. M. Athavale, Huiying Li, Yu Jiang
Cavitating flows entail phase change and hence very large and steep density variations in the low pressure regions. These are also very sensitive to: (a) the formation and transport of vapor bubbles, (b) the turbulent fluctuations of pressure and velocity, and (c) the magnitude of noncondensible gases, which are dissolved or ingested in the operating liquid. The presented cavitation model ...... hiện toàn bộ
The Fluid Mechanics of Microdevices—The Freeman Scholar Lecture
Tập 121 Số 1 - Trang 5-33 - 1999
Mohamed Gad‐el‐Hak
Manufacturing processes that can create extremely small machines have been developed in recent years. Microelectromechanical systems (MEMS) refer to devices that have characteristic length of less than 1 mm but more than 1 micron, that combine electrical and mechanical components and that are fabricated using integrated circuit batch-processing techniques. Electrostatic, magnetic, pneumati...... hiện toàn bộ
Numerical Modeling of Wind Turbine Wakes
Tập 124 Số 2 - Trang 393-399 - 2002
Jens Nørkær Sørensen, Wen Zhong Shen
An aerodynamical model for studying three-dimensional flow fields about wind turbine rotors is presented. The developed algorithm combines a three-dimensional Navier-Stokes solver with a so-called actuator line technique in which the loading is distributed along lines representing the blade forces. The loading is determined iteratively using a blade-element approach and tabulated airfoil d...... hiện toàn bộ

REVIEW—Review of Flow Interference Between Two Circular Cylinders in Various Arrangements
Tập 99 Số 4 - Trang 618-633 - 1977
M M Zdravkovich
Abstract There are infinite numbers of possible arrangements of two parallel cylinders positioned at right angles to the approaching flow direction. Of the infinite arrangements, two distinct groups may be identified: in one group, the cylinders are in a tandem arrangement, one behind the other at any longitudinal spacing; and in the second group, th...... hiện toàn bộ
Comprehensive Approach to Verification and Validation of CFD Simulations—Part 1: Methodology and Procedures
Tập 123 Số 4 - Trang 793-802 - 2001
Fred Stern, Richard L. Wilson, Hugh W. Coleman, Eric G. Paterson
Part 1 of this two-part paper presents a comprehensive approach to verification and validation methodology and procedures for CFD simulations from an already developed CFD code applied without requiring availability of the source code for specified objectives, geometry, conditions, and available benchmark information. Concepts, definitions, and equations derived for simulation errors and u...... hiện toàn bộ

Rarefaction and Compressibility Effects in Gas Microflows
Tập 118 Số 3 - Trang 448-456 - 1996
Ali Beşkök, George Em Karniadakis, William S. Trimmer
Gas microflows are encountered in many applications of Micro-Electro-Mechanical Systems (MEMS). Computational modeling and simulation can provide an effective predictive capability for heat and momentum transfer in microscales as well as means of evaluating the performance of a new microdevice before hardware fabrication. In this article, we present models and a computational methodology f...... hiện toàn bộ
