Abstract
The paper reports the computational fluid dynamics (CFD) investigations of the flow induced excitations in a high-pressure integral throttle valve. The
effect of the valve openings on the characteristics of the unsteady fluids force on
the valve head are studies. 2D CFD models are developed based on high pressure
integral throttle valve and normal operating conditions. The paper presents the
brief summary of the earlier studies from the literature, introductions on the CFD
models and the observations made from the CFD simulations. The amplitude of
the oscillating component of horizontal fluid force rapidly increase as the opening
increase from 22.5% to 50%, and remains the similar value as the valve opening
keeps increasing. There are up and downs in the relationship between the amplitude of the oscillating component of axial force and governor valve openings. The
vibration at axial direction is more likely to be excited due to the fluid force, as
more peaks show up in the spectrum of the oscillating axial fluid force.
