| | 35 | '''Description:''' \\ |
| | 36 | This animation shows the turbulent flow field generated by a single cube with an edge length of 50m. 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. The side view also shows the evolution of a roof vortex. 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. |
