in this paper, the fluid-structure interaction phenomenon and the research history are described. then due to the complex and specific working conditions of a turbine blade, we have investigated the phenomenon on this subject. the fluid-structure interaction on a turbine blade model has been simulated by using structural and fluid flow section of ansys software. a model of turbine blade with ai...

In fluid-structure interaction problems, many people use a penalty method for positioning the structure inside fluid. This is usually performed by considering that fluid very stiff or/and heavy at place occupied structure. These methods are convenient programming point of view but can lead to ill conditioned operators. drawback in numerical solution methods. particular forces applied surroundin...

In this paper, we describe a computational model for the simulation of fluidstructure interaction problems based on fictitious domain approach. We summarize results presented over last years when our research evolved from finite element immersed boundary method (FE-IBM) to actual distributed Lagrange multiplier (FEDLM) method. recall well-posedness formulation at continuous level in simplified ...
