ridt
RIDT (rapid indoor dispersion tool) is a Python implementation of two different analytical dispersion models, Eddy Diffusion and Well Mixed. It allows the calculation of concentrations and exposures based on an arbitrary set of instantaneous, infinite duration, and fixed duration source terms in a cuboid bounded system. The Well Mixed model is a set of dimensionless exponential decay equations, whereas the Eddy Diffusion model is a variant of the standard solution to the 1D diffusion equation solved with closed boundary conditions, combined in a separable product in three dimensions.
