Thermal FSI Concepts

This chapter reviews the general concepts of fluid-structure interaction (FSI), with a focus on thermal FSI. So, it is known as Thermal FSI.

It discusses two overall methodologies for simulating thermal FSI cases: Intrinsic FSI and Extrinsic FSI.

In the first approach, all calculations of the fluid and solid domains and the interaction between them are performed by the Fluent solver. For this purpose, the Structure model with enabling Thermal effects is used.

In the second approach, the calculations of the fluid and solid domains are performed separately and individually by different solvers. Then, by defining data transfer, the solvers are coupled together. For this purpose, the Fluent solver is used to solve the fluid flow, and the Structural and Thermal solvers are used to solve the solid domain.
