The unsteady cavitating flow field on a 2D hydrofoil is investigated by experimental means and numerical calculations. The self-oscillatory behavior of the cavitation sheet observed experimentally is correctly simulated by the numerical model. A particularly good agreement is obtained concerning the frequency of the phenomenon in various flow configurations. To confirm the low void ratio predicted by the model in the main part of the liquid/vapor cavity a new experimental device is applied: it is based on an endoscopic visualization of the interior of the mixture. Recent developments of the method are presented, and some first results are analysed.
