Abstract: The interaction between a semi- rigid structure and the surrounding fluid environmentis a sober issue in the stability investigation of different foil availabilities and design ofaircraft blade machinery. To Study about these types of phenomena, it requires the modelingof both fluid and structural domains. The two methods available to calculate the Fluid–Structure Interaction (FSI) effects in the time domain are the strongly coupled or partiallycoupled governing equations.In the fully coupled model, the flow field and structure respond simultaneously byexchanging the aerodynamic forces and structural displacement. Logically, the fully coupledmodel is rigorous in the physical sense, because the structural displacement respondsinstantly to the forces imposed by the fluid. In this algorithm, the fluid and structural analysisequations are combined together to form a unified set of equations. Then it is solved andintegrated simultaneously in time domain to update all the variables including those at thefluid–structure interface. This implies solving the complete system in one step; hence there isno information transfer in fully-coupled method. The fully coupled algorithm usually requiresan almost complete rewrite of the CFD and CSD codes into one single coupled code.In this project, the modeling is done in Creo Parametric 2.0 and Computational fluiddynamics analysis and fluid structure interaction (FSI) is done in ANSYS 15.0 solver. TheStatic structural analysis is carried out initially. The flow analysis of various angle of attacksare carried out and FSI is done for the respective models. The later and the former arecompared for pressure distributions and velocity magnitudes for various angles of attack. Thepressure coefficients and velocity magnitudes are comparably good for Fluid structureInteraction.
