The initial flow is laminar (from left) with a mean speed of 1 m/s, and neutrally stratified. The particle color displays the height above ground (red: high, blue: low). The wake vortex behind the building is especially dominant. Since cyclic boundary conditions along x and y are used, the turbulence generated on the lee side of the building hits the building again from the luv side after some time.\\ ||||='''Model Setup''' =|| ||Total domain size (x|y|z):||960m x 320m x 150m|| ||Grid spacing (x|y|z):||5m x 5m x 5m|| ||Number of grid points (x|y|z):||192 x 64 x 30|| ||Simulated time:||1h|| ||CPU-time:||155s|| ||Number of CPUs:||8|| ||Machine/ processor type:||NEC-SX6|| ||Visualization software:||DSVR|| \\ ||||||='''Download''' =|| ||Video Format ||File size || ||Flash (.flv) || 6.5mb||[[htdocs:gallery/movies/cube_flash.flv|Download]]|| ||MPEG (.avi) || 6.5mb||[[htdocs:gallery/movies/cube_mpeg.avi|Download]]|| ---- == Flow around a single cube II (2005) #cube2 {{{#!html }}} '''Project:''' [[imuk/projects/2003_04|High Resolution LES of Turbulent Flow in the Vicinity of Buildings including Thermal Effects]]\\ \\ '''Responsible:''' [[imuk/formermembers/letzel|Marcus Letzel]]\\ \\ '''Description:''' This animation shows the same simulation as [[#cube1|above]].
