Abstract
The present work aims to compare transitional turbulence models available in open source CFD codes when applied in low Reynolds number flows over airfoils. In order to ensure a coherent numerical comparison, a mesh convergence study is carried out. The models and codes are compared according to its proximity to the experimental pressure distributions and forces. In general, all of the codes showed good agreement, and the transitional models were capable of capturing features such as transitional bubbles that were not observed in the non-transitional models.
