Modeling Fluid-Structure Interaction with COMSOL Multiphysics®

Fluid-structure interaction (FSI) is a common phenomenon in science and engineering. FSI applications in aerospace include dynamic stalls in rotorcraft and wind turbines, drones, and flow control. Airflow can also result in structural deformation and vibrations in aircraft wings, making FSI an important phenomenon to understand and model. For accurate modeling of FSI problems, the COMSOL® software provides a built-in interface that includes a Multiphysics coupling between fluid dynamics and structural mechanics.

In this webinar, the speaker will cover several possible modeling scenarios for FSI, including one-way coupling, two-way coupling at steady state, and two-way coupling with full dynamic effects. Through interactive demonstrations, you will see how the software can be used to set up and solve one-way and two-way coupled FSI problems for both laminar and turbulent flows.

We will answer any questions you may have during the presentation or at the end during the Q&A session.

Electric vehicles (EVs) tend to be heavier than internal combustion engine vehicles due to the heavy weight of battery packs. Because of this, it is becoming increasingly important to design car structures with advanced materials that are lighter while still strong. EV lightweighting can improve vehicle range, acceleration, and braking; reduce tire wear; and increase cargo capacity. Evaluating lightweight materials as well as optimizing structural designs involves accounting for different interacting physics phenomena, including structural mechanics, thermal stresses, and acoustic wave propagation.
