Over het archief
In 2012 verloren we Jean Jacques Peters, voormalig ingenieur van het Waterbouwkundig Laboratorium (1964 tot 1979) en internationaal expert in sedimenttransport, rivierhydraulica en -morfologie. Als eerbetoon aan hem hebben we potamology (http://www.potamology.com/) gecreëerd, een virtueel gedenkarchief dat als doel heeft om zijn manier van denken en morfologische aanpak van rivierproblemen in de wereld in stand te houden en te verspreiden.
Het merendeel van z’n werk hebben we toegankelijk gemaakt via onderstaande zoekinterface.

Abstract |
For each of the rudders, two geometries are generated for which CFD computations are executed to determine the influence of geometry modifications: sharp edges chamfered, rudder and horn (combined in a spade rudder geometry). The first geometry is referred to as the ”base” configuration (with separate horn and blade), and the second is addressed as the ”simplified” configuration (spade rudder). The results are presented in terms of longitudinal force, lateral force and yawing moment coefficients, and a comparison is made between the current numerical findings and the existing experimental data The CFD results exhibit qualitatively correct trends over the investigated range of angles of attack. However, significant discrepancies are observed between the numerical and experimental data, especially for the lift coefficient. The main reasons for this are the disparity in Reynolds number between the towing tank tests and the numerical results, and the lack of inclusion of the horn in the experiments to determine the open water characteristics on the blade. |
