Fluid Surface Interaction (FSI)

AI Thread Summary
Fluid Surface Interaction (FSI) involves the interaction between fluids and solids, significantly affecting fluid flow, as seen in biomedical applications like heart valves. Thin film lubrication is a specific type of FSI relevant to human joints, such as the hip, where the fluid film thickness is comparable to the deformation of the solid structures. This area is well-studied but still not fully understood, with distinct numerical methods required for classical FSI and thin film lubrication. For literature, searching terms like "hip joint lubrication" can yield numerous resources. Overall, FSI is crucial in understanding both natural and artificial joint mechanics.

Hello all,

This is my first post on this forum, I am trying to find out about Fluid Surface Interaction (FSI), but have not found much information on it,

I have two questions at the moment:

1) Can anyone recommend any literature/books on Fluid Surface Interaction?

2) I know that FSI occurs when a fluid interacts with a solid, deforms the solid and therefore affects the fluid flow. It can occur for example in biomedical heart valves where blood flows through the heart valve. Would it be applicable in human natural and artificial joints (e.g. hip joint) where there is a fluid film rather than an a inlet-outlet type fluid flow?

Any feedback would be much appreciated

Thank-you

Hi

2)FSI at (e.g.) hip joint is called thin film lubrication. It it substantially different from classical (e.g., as you write, biomedical heart valves) FSI since the size of structures deflection is comparable with the same size of the film thickness. The topic is quite well studied by not yet completely.

1)Just try to google your application + lubrication and you will find a plenty of work on it. E.g. on hip joint http://books.google.com/books?id=V-...ook_result&ct=result&resnum=6&ved=0CDgQ6AEwBQ

ps: numerics for "classical" FSI and thin film lubrication are strongly different: many fem package can solve FSI, but very few of them can also solve the other.
 
Posted June 2024 - 15 years after starting this class. I have learned a whole lot. To get to the short course on making your stock car, late model, hobby stock E-mod handle, look at the index below.

I'm trying to decide what size and type of galvanized steel I need for 2 cantilever extensions. The cantilever is 5 ft. The space between the two cantilever arms is a 17 ft Gap the center 7 ft of the 17 ft Gap we'll need to Bear approximately 17,000 lb spread evenly from the front of the cantilever to the back of the cantilever over 5 ft. I will put support beams across these cantilever arms to support the load evenly

Scenario 1 (figure 1) A continuous loop of elastic material is stretched around two metal bars. The top bar is attached to a load cell that reads force. The lower bar can be moved downwards to stretch the elastic material. The lower bar is moved downwards until the two bars are 1190mm apart, stretching the elastic material. The bars are 5mm thick, so the total internal loop length is 1200mm (1190mm + 5mm + 5mm). At this level of stretch, the load cell reads 45N tensile force. Key numbers...
