A knowledge of the time-varying force and its distribution on the bends is highly desirable in designing the piping and piping support systems. A numerical study has been carried out to obtain an understanding of the slug flow induced forces and develop simulation models for engineering ...
Vertical component of fluid force exerted on the riser by liquid slug f Response frequency fx Horizontal vibration frequency fz Vertical vibration frequency f1x, f2x, f3x First three natural frequencies of flexible riser in x direction f1y, f2y, f3y First three natural frequencies of flexible ...
Higher momentum of liquid slug creates considerable force as it changes the direction of flow while passing through elbows, tees and other equipment. This may cause severe damage to the piping structure. Images are shown in Fig. 8 for the less aerated slugs by varying ReSG in the range of ...
There are limitations on flange class (max CL600) which may force you to use a butterfly. If so, I have had not bad luck with Keystone Vanessa 30000 series. Include a digital positioner which will at least help with the control aspect. NGiLuzzu (Mechanical) 4 Nov 03 03:23 Neil, ...
This in turn allows prediction of the probability of the largest forces that occasionally occur at various flow rates. This information is vital in designing an appropriate support for the piping system, to cater the maximum force over a long period of operation. Besides, this information is ...
Hydrodynamic loads (i.e., force-time curves) on various pipe segments have been evaluated by appropriate postprocessing of the transient results. The calculated peak forces at selected pipe segments compare favorably with those estimated from the analytical models...
In this paper, a dynamics model capable of describing the characteristics of hydrodynamic slug flow and fluid-structure interactions involving centrifugal force and Coriolis force is presented to investigate the dynamic behaviours of horizontal pipes subjected to hydrodynamic slug flow. The motion equation...
