Archief Prof. Ir. J.J. Peters

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

The hydrodynamic features of several design alternatives for the entrance of the fish passage annex to the Denderleeuw’s lock‐weir complex are studied by means of the Volume‐of‐Fluid (VoF) method using Computational Fluid Dynamics (CFD). These accessories are meant to enhance the fish attraction performance of the fish passage attached to the lock‐weir complex in Denderleeuw. Previous studies performed by Badano et al. (2019) for the fish passage in Denderleeuw show favorable currents going through the entrance of the fishpass, and overall flow velocities somewhat below the upper threshold defined by the designer. However, studies conducted here show increased flow bulking and aeration downstream of the weir, plus diminished flow attraction due to the sheer difference in specific forces between the flow exiting the fish passage and the flow produced by the weirs. The present results differ from previous studies, and may lead to different assessments. Therefore, the present work attempts to provide further explanation to the aforementioned phenomena and to critically assess the differences between the previous and the present study.
