Abstract

To visualize potential flow easily, an apparatus of Hele-Shaw flow using service water was designed and constructed. The conditions of the space between two parallel plates and the flow speed are discussed from the theoretical consideration. The apparatus is reported to realize almost exact potential flows past various shapes, circle, inclined plate and so on. The flow is checkedcomparing with the calculated streamlines and velocity around the shape. A new trial is successfully performed to generate circulation around a shape. The flow past an inclined foil is able to satisfy socalled Kutta condition at the trailing edge. The apparatus realizing the potential flow with and without circulation may be utilized to recognize the basis of hydrodynamics.
