Ideal fluid flow past obstacles in an arbitrary channel: comparison of numerical and experimental results

This paper analyses a numerical model of a flow around an obstacle bounded in a channel with arbitrary walls. The model is based on the usual two-dime nsional model of ideal incompressible weightless fluid. It is validated her e by comparison with analytical findings and experimental data, which consi sted of the velocity field determined by particle image velocimetry (PIV). Despite the simplicity of our wake model, the numerical data are usually in good agreement with the analytical and experimental data.
