Abstract
After an introduction to the underlying problem, the governing equations and discretisation schemes, we present in the first part of this contribution the calculation of the model and discretisation error in a turbulent natural convection flow in a tall cavity. It is based on uniform grid refinement and explicit values are given for the error components. In the second part we apply for the same problem local grid adaptation using four different a posteriori error indicators. The computational results are compared with experiments and it is shown, that adaptively refined grids with considerably less elements deliver comparable results gained on finer uniformly refined grids.
