Numerical modelling as a tool for optimisation of sub-slab depressurisation systems design

The following paper is focused on possibilities of a numerical modelling of sub-slab depressurisation systems, which belong among the most effective radon protective measures. Three recently developed computer programs are briefly described in the paper—mainly from the point of view of governing equations and basic numerical analysis approach. The paper also presents results of sensitivity tests for these numerical models. In addition, a comparison of numerical simulation results with measured data is included as well.
