Air Quality Modelling: Gaussian Plume Model - Examrace (Dr. Manishika) Env. Air Pollution

50 ratings | 1382 views
Dr. Manishika Jain explains Air Quality Modelling: Gaussian Plume Model • Steady-state conditions - rate of emission from the point source is constant. • Homogeneous flow - wind speed is constant both in time and with height (wind direction shear is not considered). • Pollutant is conservative and no gravity fallout. • Perfect reflection of the plume at the underlying surface, i.e. no ground absorption. • The turbulent diffusion in the x-direction is neglected relative to advection in the transport direction, which implies that the model should be applied for average wind speeds of more than 1 m/s (less than 1 m/s). • The coordinate system is directed with its x-axis into the direction of the flow, and the v (lateral) and w (vertical) components of the time averaged wind vector are set to zero. • The terrain underlying the plume is flat • All variables are ensemble averaged, which implies long-term averaging with stationary conditions.

Thank you for taking the time out and making a video on it. Can't wait for next one on Time dependent models. This video will be of great help, even though I went through tons of powerpoint slides, I couldn't fully understand those slides. I needed the crisp, to the point video. :)
