In the center of the program window, we will draw and we will calculate the different polluting processes. We can draw using two different planes: parallel to the ground surface (XY) and perpendicular to the ground surface (XZ). There is a grid in the XY-plane. The coordinate origin is on the left bottom corner (X=0, Y=0) in XY-planes (parallel to the ground surface). In addition, the coordinate origin is on the left bottom corner (X=0, Z=0) in XZ-planes (perpendicular to the ground surface).
XY-Planes (parallel to ground surface):
In such a case, the program window is a XY-plane (parallel to the ground surface). A pollutant point source (stack) is represented by a small square. In the Status bar at the bottom, we have X,Y and Z coordinate values in meters and data on our environmental system. Point the mouse where you want in the program window and the X,Y and Z values will be shown in the status bar at the bottom. If you select XY-Plane, a grid appears. On the left bottom corner, two different text boxes appear: The position of the XY-plane with respect to the ground surface (XY-plane height) and the pollutant concentration value (micrograms per cubic meter, ug/m3). Point the mouse where you want in the program window and the concentration value will be shown in the text box. The pollutant concentrations will be calculated in a parallel plane to the ground surface (XY-Plane). The plane height will be determined by the user (zr).
All the points of the XY-plane will be to a zr height. The zr value is chosen by the user before the calculation. We will be able to make many calculations considering different plane heights. The different plane heights will be determined by the user (zr values). In this way, the physical form of the pollutant plume can be studied.
Air pollution map (XY-Plane) produced by continuous discharge in time. The fucshia lines represents a stacks in the XY-Plane. The red colour represents high pollutant concentrations. Winds: four different winds.
Air pollution map (XY-Plane) produced by continuous discharge in time. The red colour represents high pollutant concentrations. Wind: E (90 degrees).
Pollution: Pollutant point sources are represented by a small square in the program window. The air pollution can be evaluated in our environmental system to generate different environmental reports. High pollutant concentrations can be represented with colours.
