Lattice Boltzmann simulation of two-sided lid-driven flow in deep cavities
The present study is concerned with two-sided lid-driven incompressible flow in rectangular, deep cavities applying lattice Boltzmann method. After validating the code for the square cavity, solutions for cavities with an aspect ratio 1.5 and 4 were obtained for the Reynolds numbers of 100,...

| description | The present study is concerned with two-sided lid-driven incompressible flow
in rectangular, deep cavities applying lattice Boltzmann method. After
validating the code for the square cavity, solutions for cavities with an
aspect ratio 1.5 and 4 were obtained for the Reynolds numbers of 100, 400,
1000 and 3200. The influence of the Reynolds number and aspect ratio on the
flow pattern and on the characteristics of vortices inside the cavity was
studied. Symmetric flow pattern was obtained for all investigated cases. The
middle of the cavity is mostly influenced by the increase in the aspect
ratio. Critical aspect ratio, at which the birth of a primary vortex in the
middle of the cavity takes place, was determined to be between 2.7 and 2.725.
