ENDUSE DISPLAY Library case I107: EXHAUST DISPERSION NEAR A TOWER BLOCK This Q1 is an example of modelling urban pollution. The wind flows around a 31-storey tower block with a low rise block on the other side of the street. The source of pollution comes from the vehicular exhaust. The road passes between two residential blocks. Although FLAIR does not have capability of automatically setting wind profile, this example shows that the same effect can be achieved by defining several 'fans' with height-dependent inflow. The only non-standard setting is switching-off buoyancy Patch which has to be done from a command-mode level by typing: BUOYANCY=SKIP. (Use PHOTON to display results. Enter USE Q1 in PHOTON command mode, or create a file called U, which contains the one line: USE Q1 before typing RUNPHO.)
