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 |
Computations are executed according to the specifications of the International Towing Tank Conference (ITTC), where the angular velocity of the propeller remains constant and results are computed for a range of advance ratios ? by altering the forward velocity of the propeller. This contrasts with the recommendations of NUMECA for open‐water computations, where the forward velocity is held constant, and the advance ratio is changed by altering the angular velocity of the propeller. Computations are executed in a rotating frame of reference which allows for larger time steps than in a fixed frame of reference. The by NUMECA recommended time step values were however not strict enough for low values of the advance ratio: the smallest value used is 1/8 of the recommended value. A comparison between the numerical results and the reference values shows a good agreement. This type of computation could be used in the future as an alternative to experimentally determined open‐water propeller characteristics if a solution is found for the slow convergence at ? = 0. |
