"Several discretisation scheme

"Several discretisation schemes have been added for better accuracy and better stability on 'bad' (e.g. tetrahedral) meshes."
I would like to know which are the best schemes to use with 'bad' meshes. Also, I tried to simulate the flow of a low viscosity fluid with icoFoam on a tetrahedral mesh and the results were OK. However, when I increase the viscosity, there are stability issues (velocity field reaches extremely high values). Does anyone know why viscosity influences stability?
