Downwash Analysis Tool |
|
An add-on utility is now available (contact BREEZE sales for pricing information) to show the zone of influence around obstructions to wind flow (e.g., buildings).
BREEZE Downwash Analyst is a tool to help AERMOD dispersion modelers 1) visualize and better understand how BPIP (Building Profile Input Program) generates the BPIPs (Building Profile Input Parameters) used by PRIME (Plume Rise and Building Downwash Model), and 2) visualize and better understand how the BPIPs are used by PRIME to compute the cavity and wake geometry used to modify plumes (i.e. induce downwash) within AERMOD.
In general, the BPIP processor produces two results:
| 1. | The maximum GEP (Good Engineering Practice) stack height for each stack as a function of the neighboring building geometry and 1440 wind directions. |
| 2. | The maximum HWE (Height of Wake Effect) and the BPIPs (Building Profile Input Parameters - height, width, length, X-shift, and Y-shift) for 36 wind directions around each stack. |
More information regarding this utility can be found in the online user manual.
