Abstract
Two different methods to obtain nearly grid independent solutions for tip vortex flow were tested for a wing and a propeller. A priory mesh refinement inside a tube with a helix shaped centre line worked quite well, reducing the grid dependency of the minimum pressure in the vortex core significantly but the accuracy still depends on the initial mesh. Better results were obtained with adaptive mesh refinement using the jump based estimator. Projection of new created nodes to the exact geometry is required to obtain high accuracy.
