Abstract
The convective-diffusion equation is the governing equation of many important transport phenomena in building physics. The paper deals in its first part with the general formulation of the convective-diffusion equation and with the numerical solution of this equation by means of the finite element methods. The second part of the paper contains the analysis of one typical combined transport problem - the combined heat transfer through the building constructions caused by conduction and convection. The finite element solution of this problem is presented in the paper together with the numerical stability analysis and one practical example of the numerical analysis of a model lightweight building construction. The results of the model analysis demonstrate that the lightweight constructions insulated with permeable mineral wool are very sensitive to the convective heat transfer.
