Gaussian Plume Java Applet

Using this Applet

This applet provides a number of slider bars to change parameters:
  1. wind speed
  2. stack height
  3. stack diameter
  4. emission rate
  5. gas temperature
  6. gas velocity
  7. atmospheric temperature
  8. atmospheric conditions
  9. 3D coordinates and graphics resolution
To change the values, simply slide the slider bar. Alternatively, you can type in a value and hit the Enter/Return key.

Output is provided in several formats: x-y graph, top and side view visualizations, and text-based output. In the side-view format, the black bar on the left of the graphics window shows the stack, changing in height as the stack height slider bar is modified. In the top-view format, the stack is seen as a black dot, half-way up the y-axis.

The x-y-z contour plot range sliders help to zoom in and out of the plume. The z-contour plot only modifies the side-view, while the y-contour slider only modifies the top view. The x-contour modifies both top and side views.

You need to have a java enabled browser like Netscape Navigator 4 to view this java applet.
