【Abstract】 Numerical modeling was performed to investigate the vortex precession in swirlmeter. A FVM analysis software FLUENT was applied to analyze the vortex precession in swirlmeter. At last, through comparing the results of experiments with the results of simulation, the errors of simulation are attained; the path to improve simulation accuracy is advanced.更多还原
