Lid-driven cavity flow has been widely used to validate CFD codes. The problem consists of a 2-D rectangular cavity filled with fluid that is covered by a horizontal moving lid. The case has been studied among others including Ghia et al. 1982, Ku et al. 1987 & Chern et al. 2005.
Herein just the case of Re=1000 is considered, as well as the resolution of 100x100 particles. For further details see the official validation test web page.
- n = 100x100
- Δr = 1.0x10-2m
- h / Δr = 4
- α = 0.0
- δ = 1.0
- cs = 50m/s
- Δt = 2.0x10-4s
- p0 = 3.0Pa
- Re = 1000
- BCs: Boundary integrals, No-Slip
- No turbulence model
Following you can see the original streamlines figure extracted from the SPHERIC validation test web page, overlapped with the velocity glyphs resulting from SPH:
The color denotes the velocity magnitude (blue = 0m/s, red = 1m/s).
Regarding the velocity profile, in the following figure the original results presented by Chern et al. 2005, are compared with the computed with AQUAgpusph:
It should be noticed that, even with this coarse resolution, a good agreement is achieved. A video of the simulation can be viewed in the AQUAgpusph gallery.
