Flow visualisations for some selected MITRAS simulations

a) Visualisation of the complex flow structure within an idealized districtShown are the flow structure in a street canyon between two buildings and the recirculation zone behind a building.

b) Visualisation of the flow structure around a cube - wind direction ist perpendicular to the front faceShown are the incoming flow profile and flow pattern in front of the cube including the front and horseshoe vortex. In the second part the flow pattern in the cavity zone is visualized.

c) Visualisation of the flow structure around a cube - wind direction ist 45 degrees to the front faceShown are the incoming flow profile and flow pattern in front of the cube including the front and horseshoe vortex.

d) Simulation of a tracer experiment in an urban street canyonShown is the dispersion of tracer particles in a complex street canyon for numerous wind directions (see table).
