Source data:

The Point source Menu lists the possible pollutant sources: the point source, line source and area source.

 

Point source:

Point source.- This is a pollutant point source. The stack size is small if we compare it with the size of the area in which we are simulating (point source). If you click this button, the next dialog box is shown:

 

 

The necessary data is:

Physical stack height (m): This is the physical stack height in meters.

Stack gas exit velocity vs (m/s): This is the stack gas exit velocity. It can be around 15 m/s.

Stack gas exit temperature (K): The discharge concentration of the material of interest (pollutant or tracer) is defined as the excess concentration above any ambient concentration of that same material. 1g/m3=1ppm in air.

Stack inside diameter (m): This is the stack inside diameter.

Pollutant emission rate (g/s): This is the pollutant emission rate.

Decay coefficient (1/s): This coefficient considers the half life of the pollutant if this disappears by means of chemical reactions (non-conservative pollutant).

Estimate flow rate: With this button, you can estimate the pollutant flow rate if it is unknown. If you know the rate, you don't need to use this command. You can write it directly in the point source window. If you click this button, the next dialog box is shown:
