Fluid Structure Interaction- Wide Application Area

CADM Outsourcing offers Fluid Structure and Interaction Analysis to enhance fluid characteristics and resolve engineering modeling errors.

Fluid Structure Interaction or FSI happens when the fluid flow causes any deformation of the structure. The deformation can lead to changes happening in the boundary conditions of the fluid flow.

FSI is one of the most challenging multi-physics problems with respect to the modeling and computational issues. This interaction is considered as the crucial one in many engineering system e.g. construction of bridges, aircrafts. FSI can be stable or oscillatory.

In the oscillatory interactions, the strain that gets induced in the solid structure makes it to move in such a manner that the strain source is reduced and the structure comes back to the previous state and the process gets repeated again.

If the FSI interactions e.g. oscillating interactions are not considered properly then it could be very damaging. e.g. the structures that are created with the materials susceptible to fatigue – bridges, the aircraft wings and blades of turbines can also break due to FSI oscillation.

The important of FSI is there in the health industry also. During the analysis of artificial heart valves and aneurysms in large arteries, the FSI analysis should be taken into consideration. 

FSI is difficult to get solved analytically so they are basically analyzed with the help of numerical simulation or through various experiments. There are number of researches that are still going on in the fields of computational structural dynamics and fluid.

There are two different approaches that are there for the simulation of fluid structure interaction problems:

• Monolithic Approach - with the help of the single solver, the equations controlling the flow and displacement of the structures are solved.
• Partitioned Approach - the two separate equations controlling the flow and the displacement of the structure gets solved separately with two different solvers.

The application area of FSI is wide:

• Aerospace application e.g. turbine engines, airfoil flutter
• Biomedical applications e.g. intravenous catheters, elastic artery modeling used for stent design
• Automotive applications e.g. heat exchangers, HVAC heating or cooling
• Fluid handling applications e.g. pressure regulators
• Applications of civil engineering
• Electronics cooling
