Fluid Power System Dynamics - University of Minnesota

Fluid power is the transmission of forces and motions using a confined, pressurized fluid. In hydraulic fluid power systems the fluid is oil, or less commonly water, while in pneumatic fluid power systems the fluid is air. Fluid power is ideal for high speed, high force, high power applica-tions.

Dynamic Analysis for an Internally Coupled Fluid/Riser ...

A top-tensioned riser generally consists of outer casing, inner casing and tubing. The pipes are coupled either through fluids in the annuli or through intermediate guides (centralizers) or through both. This paper investigates the dynamic analysis for such an internally coupled fluid/ riser system.

Vortex-induced vibration dynamics of a flexible fluid ...

A van der Pol wake oscillator is adopted to represent the fluctuating lift forces, and nonlinear hydrodynamic force is also introduced. The goal of the present work is to discuss VIV dynamic responses of a fluid-conveying riser to guide the design and usage of riser in offshore oil field.

Comparisons of particle cluster diameter and concentration ...

Abstract−The information of particle cluster dynamics is necessary for improving the performance of a circulating fluidized bed system. The main objective of this study is to compare the particle cluster diameters and concentrations from computational fluid dynamics simulation results between circulating fluidized bed riser and downer.

Dynamic Analysis for an Internally Coupled Fluid/Riser ...

An effective dynamic stiffness matrix method is then developed to evaluate the added mass and damping influence of the fluid on the natural frequencies and the dynamic response of the coupled riser system. A riser example is used to illustrate the fluid coupling impact on the system's dynamic …

Dynamic Responses of Marine Risers/Pipes Transporting ...

This paper deals with the dynamic responses to top end excitation of marine risers/pipes conveying internal fluid. The marine riser is often used as a flexible link between undersea bore head and subsurface offshore platform. The tidal waves and the changes of sea level consistently excite its top end connected to a floating vessel.

Dynamics and Control for Deep-Sea Marine Risers

Dynamics and Control for Deep-Sea Marine Risers A marine riser is a pipe that connects a floating platform such as an oil rig or drillship on the ocean surface to the sea floor. Used as a fluid conveyer, it transports undersea energy resources from the seabed to the platform on the surface. Marine risers …

Dynamic Analysis for an Internally Coupled Fluid/Riser System

This paper investigates the dynamic analysis for such an internally coupled fluid/ riser system. This paper first presents a theoretical formulation for a general riser system coupled with fluids in the annuli and centralizers between pipes. Hydrodynamic forces associated with the viscous fluid in between concentric cylinders are considered.
