Introduction (lid-driven cavity)
The lid-driven cavity flow is absolutely one of the most investigated problems in the field of fluid mechanics and computational fluid dynamics. Lid-driven cavity flow contains different physical phenomena including vortex and recirculating regions depending on the Reynolds number. Here, we have considered a square cavity. The top wall is moving while the other walls are stationary. The flow regime is laminar and we determine this by specifying the Reynolds number.
Steps in the simulation of lid-driven cavity
In this section, you will learn how to set up and solve two-dimensional laminar flow in a lid-driven cavity. Consider a mesh that you have already implemented in Fluent and then investigate it in terms of size and quality. Then, add a new material from the database. Next, set the boundary conditions and specify solver settings and start the iterations, Finally, study results and compare them with experimental data. We investigate streamlines and also its animation.
you can find flow simulation training files in a lid-driven cavity below to download. In order to discuss and investigate problems in a cavity with moving boundary conditions, you can use the forum and ask you questions. After discussion, your final answer will be given by the director.
