The lid-driven cavity problem has long been used a test or validation case for new codes or new solution methods. The problem geometry is simple and two-dimensional, and the boundary conditions are also simple.

2018年5月8日 · Learn how to solve a CFD benchmark, the lid-driven cavity problem, in COMSOL Multiphysics® with techniques such as mapped meshing and nonlinearity ramping.

The standard model with wall functions will be used in this tutorial to solve the lid-driven cavity case with a Reynolds number of . Two extra variables are solved for: , the turbulent kinetic energy; and, , the turbulent dissipation rate.

The lid-driven cavity is a well-known benchmark problem for viscous incompressible fluid flow . The geometry at stake is shown in Figure 27 . We are dealing with a square cavity consisting of three rigid walls with no-slip conditions and a lid moving with a tangential unit velocity.

2017年3月1日 · This paper presents a broad account of the lid-driven cavity flow problem which is an important benchmark problem for the validation of CFD codes.

2024年9月23日 · The lid-driven cavity problem is a classical benchmark in computational fluid dynamics (CFD) used to study the behaviour of incompressible viscous flow inside a square cavity.

The lid-driven cavity is a classical fluid dynamics problem. It consists of a flow in an enclosed cavity, where one of the walls (in this example, the top wall) is put in motion at a constant tangential velocity.

We will use the “interpolate” option in Fluent. This allows to write solutions computed on a given grid and read (interpolate) them on any other grid (finer/coarser). Problem: only saves pressure/velocity/scalar data... Workaround: save the solution (let’s say the x-velocity) in a “dummy” scalar field using a UDF.

2018年4月10日 · The lid-driven cavity is an important fluid mechanical system serving as a benchmark for testing numerical methods and for studying fundamental aspects of incompressible flows in confined...

This tutorial illustrates the setup and solution of a two-dimensional incompressible laminar flow in a lid-driven cavity.
