The paper presents selected problems of numerical modelling of intensification cases of the convective heat transfer in pipe channels with turbulisers. The example of water flow with ball shaped turbulisers through a vertical, copper pipe, externally heated by water vapour condensation heat, is used to present the rules and guidelines for a numerical model construction in the manner existing in the state-of-art CFD codes. This model, its implementation and numerical results has been verified against an experimental data with satisfactory agreement. /
