Gaussian Plume Models can be used in several fluid dynamics scenarios to calculate concentration distribution of solutes such as a smoke stack release or contaminant released in a river. Gaussian distributions are established by Fickian Diffusion, and follow a gaussian (bellshaped)distribution .[1]For calculating the expected concentration of a one dimensional instantaneous point source we consider a mass M released at an instantaneous point in time, in a one dimensional domain along x. This will give the following equation:[2]
Where M is the mass released at time t=t0 and location x=x0, and D is the diffusivity[m^2/s]. This equation makes the following four assumptions[3]:
1) The mass M is released instantaneously
2) The mass M is released in an infinite domain
3) The mass spreads only through diffusion
4) Diffusion does not vary in spaceReview:
1) Although this page is titled plume for fluid dynamics, I thought that they covered the most general aspects of plumes for gaussian modeling, and perhaps needed more specifics like equations, and modelling scenarios to make it more comprehensive
2) Since Gaussian Plumes was the topic that I was focusing on, the page has more information on it than any other plumes that were briefly introduced. This may make the Gaussian Plumes overrepresented in the page, so contributions to other types of plumes would make the article more balanced.
3)In the future, I think I would add more equations (for 3-D) and diagrams, but with my limited knowledge on editing wikipedia pages, I would prefer to leave things as it is for now.
