TL;DR: The mathematical basis of TWODEE, the Health and Safety Laboratory's shallow layer model for heavy gas dispersion, is described, which is a compromise between the complexity of CFD models and the simpler integral models.

TL;DR: This paper compares results of the TWODEE model to the experimental results taken at Thorney Island and concludes that there is no evidence to suggest that TWODee predictions could be improved by changing any of the entrainment parameters from generally accepted values.

TL;DR: The numerical solution method used to simulate the TWODEE mathematical model is developed and the boundary conditions for the leading edge, discussed in part 1, make demanding requirements on the computational scheme used.
