Mr-CFD offers a complete range of CFD analysis, consulting services and training in fluid-structure interaction (FSI)
Fluid-structure interaction is the science of investigating fluid flows interacting with structures. And the occurred phenomena in the interaction. Moreover, Fluid-structure interaction (FSI) has a wide range of applications in many engineering systems.
We use the FSI model just for cases that fluid and solid behavior are completely coupled and the reason for stress in a structure depends on pressure distribution of fluid flow behavior. If pressure distribution around solid structural is uniform and by changing deflection is constant and is independent to fluid flow behavior, we do not suggest use FSI model because the complexity and computational cost of FSI simulation are higher than fluid flow analysis or structural analysis. Even some times is higher than the sum of total computational cost. So we suggest simulating the project by the FSI model just in non-uniform pressure distribution (based on fluid flow behavior) and in cases that by changing deflection pressure distribution will be changed.
There are two methods for solving the FSI problem. One way and two way. In one way method, CFD solver software (ANSYS Fluent) steadily predict pressure distribution around solid structure and this pressure distribution will transfer to structural analysis software (ANSYS static structural) and based on this, stress distribution and in consequence final strain and deflection of structure will be predicted. This method is appropriate for analysis of fluid flow behavior around building and finding final deflection of building. However, in the two-way analysis FSI method, the simulation will be done in transient mode and in each time step pressure will transfer to structural software and deflection will transfer to CFD solver. This method will be used in various industrial and aerodynamic application such as wing fluttering and Coriolis flowmeter. Etc.
We are highly experienced in the simulation of FSI problems and we use ANSYS Fluent package for solving this problem. ANSYS Fluent software is used for modeling fluid flow behavior beside, static structural and transient structural is used for modeling and simulating strain and stress analysis. In the following, there is a summary of our FSI project:
- simulation of stress and strain analysis of blood vessel in variable blood velocity
- Predicting final deflection and fluctuation of high altitude and skyscraper.
- Human heart stress analysis while pumping blood in a human vessel
- Generating power from sea wave in beach using flexible structure
- Stress and stress analysis of tidal turbine in submerged and submerged situation
- Airplane wing fluttering in turbulence fluid flow
- The fluctuation of structure in vortex shedding region
For instance, fluid-induced vibration (FIV) which is an FSI problem, is widely encountering in various applications. Such as pipes conveying fluids, cross-flow or parallel flow around solitary cylinders, vibrations related to pressure waves in piping, Surging in compressors, etc.
The phenomena of interaction between fluids and structures may occur in internal and external flow through a complex process. This can happen by numerous factors such as the structure geometry, flow conditions, and fluid properties. Our CFD engineers at Mr CFD Company believe that in order to apply the possible advantages to industry and overcome existing disadvantages, it is necessary to scrutinize effective factors.
Recent developments in the FSI field have provided mathematical and computational requirements for better understanding resulting in more effective CFD simulations. Eventually, the CFD simulations will lead to more efficient mechanical systems and help you improve the design of your systems.
