Experimental and numerical study of mean zonal flows generated by librations of a rotating spherical cavity
librations rotating spherical cavity
2011/9/7
We study both experimentally and numerically the steady zonal flow generated by longitudinal librations of a spherical rotating container. This study follows the recent weakly nonlinear analysis of Bu...
Numerical study on three-dimensional flow field of continuously rotating detonation in a toroidal chamber
continuously rotating detonation three-dimensional flow field structure numerical study detonation parameters deficit effects of wall geometries
2012/2/24
Gaseous detonation propagating in a toroidal chamber was numerically studied for hydrogen/oxygen/ni-trogen mixtures. The numerical method used is based on the three-dimensional Euler equations with de...
A numerical study on the free-surface channel flow over a bottom obstacle
open channel flow undular hydraulic jump
2010/3/11
This paper presents the results of a numerical study on a two-dimensional freesurface channel flow over a bottom obstacle. Of main interest is the capability of commercial CFD codes to solve such prob...
Numerical Study of Grid Distribution Effect on Accuracy of DQ Analysis of Beams and Plates by Error Estimation of Derivative Approximations
differential quadrature grid structure truncation error high-order boundary value problems
2010/10/22
The accuracy of global methods such as the di erential quadrature (DQ) approach is usually sensitive to the grid point distribution. This paper is to numerically study the e ect of grid point distribu...
