gaussianPlume Steady-state gaussian plume distribution model gaussianPlume models the dispersion of a continuous point source, i.e. plume, in various conditions and terrains. The output of gaussianPlume is a 3-dimensional matrix containing the concentrations of the emitted substance over a field with the first dimension (y) representing the cross-wind axis, the second dimension (x) the downwind distance, and the third dimension (z) the vertical axis. The origin is set at the base of the stack. All units are in (meters, grams, seconds) except where noted. C = gaussianPlume(Q) returns the steady-state Gaussian distribution model of a single, continuous point source emitting at a rate of Q grams per second for a 50m physical stack height with no calculations for plume rise, in rural terrain with stability class "F" in the Guifford-Pasquiill scale. Wind speed is assumed to be 1m/s at the stack tip (50m). C = gaussianPlume(Q, u_ref) sets the wind at 1m to be u_ref C = gaussianPlume(Q, u_ref, h) sets the stack height to h [C, z0] = gaussianPlume(...) returns the effective stack height in meters as z0. C = gaussianPlume(Q, u_ref, h, ...) allows you to set certain options. Options are set by 'option', pairs except for certain options which require no . The list of permissible options are listed below: {'h_ref', h_ref} Sets the reference height for the wind speed u_ref in meters. Default is 1m. {'stability', 'class'} Sets Guifford-Pasquill stability class to class 'class'. 'class' must be one of 'A', 'B', 'C', 'D', 'E', or 'F'. Default is 'F'. {'terrain', 't_type'} Sets the terrain to one of 'rural' or 'urban'. Default is 'urban' {'p', p} Sets the scaling factor for change in wind as a function of altitude to p. Default is 0.4. {'plum_rise_model', 'model'} Sets the model to use for calculation of plume rise. 'model' is one of 'none', 'CONCAWE', 'CarlsonMoses', 'Holland', or 'Briggs'. Default is 'none'. {'mw', mw} Sets the molecular weight of the exhaust for plume rise calculations. Specify in atomic mass units. Default is average of air, 30g/mole. {'amb_temp', Ta} Sets the ambient temperature in degrees Celsius. Default is 25C. {'stack_temp', Ts} Sets the stack temperature in degrees Celsius. Default is 200C. {'stack_diameter', ds} Sets the stack diameter (in meters). Default is 20m. {'specific_heat', Cp} Sets the specific heat of the exhaust gas in J/degree Celsius/g. Default is 1.020 (constant pressure Cp for dry air) {'amb_pres', Pa} Sets ambient pressure in millibars. Default is 1010mb. {'stack_pres', Ps} Sets stack tip pressure in millibars. Default is 1010mb. {'vs', vs} Sets stack exit velocity in m/s. Default is 1m/s. {'eta', eta} Sets the lapse rate for stable conditions (class E or F). 'reflection' enables ground reflection (no option value) 'noreflection' disables ground reflection (no option value) 'deposition' models dry deposition (no option value) 'nodeposition' disables dry deposition (no option value) {'vt', vt} Sets terminal/settling velocity in m/s. Default is settling velocity for PM2.5, 0.5cm/s. {'X', x} Sets sampling points at the downwind distances. x is a vector specifying the downwind distances to evaluate for C in meters. Default is 0 to 5km in 100m resolution. {'Y', y} Same as above except for the y-axis (cross-wind) {'Z', z} Same as above except for the vertical axis Example ------------------------------ C=gaussianPlume(500, 5, 50, 'h_ref', 10, 'noreflection', ... 'nodeposition', 'amb_pres', 1103, 'amb_temp', 22); Computes the steady-state Gaussian-distribution of an emission at a rate of 500g/s with average wind speed of 5m/s at 10m from a physical stack height of 50m. No plume rise, reflection, nor deposition will be modeled. The data will be sampled in 100m resolution across the downwind and crosswind axes from 0 to 5km and 0 to 1km in the vertical axis.
