FSI (Fluid Structure Interaction) – ANSYS Fluent Training Package, 5 Practical Exercises

Description

Fluid Solid Interaction (FSI) ANSYS Fluent CFD Simulation Training Package

This CFD training package is prepared for BEGINNER, INTERMEDIATE, and ADVANCED users of ANSYS Fluent software who are interested in the FSI modules, including 5 practical exercises. You will learn and obtain comprehensive training on how to simulate projects. The achieved knowledge will enable you to choose the most appropriate modeling approaches and methods for applications and CFD simulations.

Watery equipment

Project number 1 investigates the water flow around a vertical water turbine considering unsteady CFD simulation. In the present case, it is assumed that the turbine blades are affected by the flow of the passing fluid; that is, the fluid flowing through the turbine blades impedes forces on the turbine body, and these forces cause deformation or resizing of the body of these blades. Therefore, the present problem consists of two fluid and solid solutions at the same time, and hence, the FSI method and the coupling between the fluid flow and the Transient Structural are used.

Project number 2 simulates a spherical ball’s behavior in water flow using the FSI method in the last watery equipment. We perform this simulation using FSI (fluid-solid interaction) method. In this simulation, a computational domain is designed in the form of a horizontal tube filled with water flow; So that a solid or spherical object in the shape of a ball is immersed in it.

Aerial Equipment

Project number 3 simulates the airflow around an Airfoil using the Fluid Solid Interaction (FSI) method. Due to the fact that this airfoil is moving in the air at a considerable speed, the airflow collides with its body and exerts a force on it. As a result, we can say that a two-way confrontation occurs between the fluid and the solid. The UDF was used to determine the variable velocity and the variable attack angle. Finally, to make a connection or coupling between fluid and solid and to define their effect on each other, data transfer must be specified.

Blood Vessel (FSI)

In project number 4, a blood vessel with its wall has been simulated. Also, the wall displacement is considered. For the inlet boundary condition,  We have defined the pulse velocity using UDF, and for the outlet, the pulse output pressure is defined using UDF. With some differences, in project number 5, the same simulation is performed considering the pulse velocity using UDF for the input and the output in atmospheric pressure.

You can obtain Geometry & Mesh file and a comprehensive Training Movie that presents how to solve the problem and extract all desired results.
