This paper presents the first study on application of the optical flow method to aerated stepped spillway flows. For this purpose, the flow is captured with a high-speed camera and illuminated with a synchronized LED light source. The flow velocities, obtained using a basic Horn-Schunck method for estimation of the optical flow coupled with an image pyramid multi-resolution approach for image filtering, compare well with data from intrusive conductivity probe measurements. Application of the Horn-Schunck method yields densely populated flow field data sets with velocity information for every pixel. It is found that the image pyramid approach has the most significant effect on the accuracy compared to other image processing techniques. However, the final results show some dependency on the pixel intensity distribution, with better accuracy found for grey values between 100 and 150.}, language = {en} } @article{OertelBung2015, author = {Oertel, Mario and Bung, Daniel B.}, title = {Numerische Str{\"o}mungssimulationen von Fließgew{\"a}ssern : Praxisanwendungen und zuk{\"u}nftige Entwicklungen}, series = {Korrespondenz Wasserwirtschaft : KW}, volume = {8}, journal = {Korrespondenz Wasserwirtschaft : KW}, number = {H. 3}, publisher = {Gesellschaft zur F{\"o}rderung der Abwassertechnik}, address = {Hennef}, issn = {1616-430X}, pages = {177 -- 182}, year = {2015}, language = {de} } @article{DoeringRegerKuhnhenneetal.2015, author = {D{\"o}ring, Bernd and Reger, Vitali and Kuhnhenne, Markus and Feldmann, Markus and Kesti, Jyrki and Lawson, Mark and Botti, Andrea}, title = {Steel solutions for enabling zero-energy buildings}, series = {Steel Construction - Design and Research}, volume = {8}, journal = {Steel Construction - Design and Research}, number = {3}, publisher = {Ernst \& Sohn}, address = {Berlin}, issn = {1867-0539}, doi = {10.1002/stco.201510029}, pages = {194 -- 200}, year = {2015}, language = {en} } @article{EgnerHeydeLaumannetal.2015, author = {Egner, Ralf and Heyde, Stefan and Laumann, J{\"o}rg and Prokop, Ines}, title = {Vorschl{\"a}ge f{\"u}r eine anwenderfreundliche und praxistaugliche Novellierung der allgemeinen Bemessungsregeln und Regeln f{\"u}r den Hochbau (EN 1993 Teil 1-1)}, series = {Stahlbau}, volume = {84}, journal = {Stahlbau}, number = {10}, publisher = {Ernst \& Sohn}, address = {Berlin}, issn = {1437-1049}, doi = {10.1002/stab.201510321}, pages = {811 -- 822}, year = {2015}, language = {de} } @article{OertelBung2015, author = {Oertel, Mario and Bung, Daniel B.}, title = {Stability and scour development of bed material on crossbar block ramps}, series = {International journal of sediment research}, volume = {30}, journal = {International journal of sediment research}, number = {4}, publisher = {Elsevier}, address = {Amsterdam}, issn = {1001-6279}, doi = {10.1016/j.ijsrc.2014.12.003}, pages = {344 -- 350}, year = {2015}, abstract = {Block ramps are ecologically oriented drop structures with adequate energy dissipation and partially moderate flow velocities. A special case is given with crossbar block ramps, where the upstream and downstream level difference is reduced by a series of basins. To prevent the total structure from failing, the stability of single boulders within the crossbars and the bed material in between must be guaranteed. The present paper addresses the stability of bed material and scour development for various flow regimes. Any bed material erosion may affect the stability of the crossbar boulders, which in turn can result in major damages of the ramp. Therefore new design approaches are developed to choose an appropriate bed material size and to avoid failures of crossbar block ramp structures.}, language = {en} } @article{LeandroBungCarvalho2014, author = {Leandro, J. and Bung, Daniel B. and Carvalho, R.}, title = {Measuring void fraction and velocity fields of a stepped spillway for skimming flow using non-intrusive methods}, series = {Experiments in fluids}, journal = {Experiments in fluids}, number = {55}, publisher = {Springer Nature}, address = {Heidelberg}, issn = {0723-4864 (Print) ; 1432-1114 (Online)}, doi = {10.1007/s00348-014-1732-6}, pages = {Art. 1732}, year = {2014}, language = {en} } @article{MalechaKlubertHeinenFuchs2014, author = {Malecha, Hartmut and Klubert, J. and Heinen-Fuchs, Sabine}, title = {Laserscanning passe? 3-D-Oberfl{\"a}chenmodelle aus Bilddaten und deren messtechnischer Nutzen}, series = {Wasserwirtschaft}, volume = {Jg. 104}, journal = {Wasserwirtschaft}, number = {Nr. 9}, publisher = {Springer Vieweg}, address = {Wiesbaden}, issn = {0043-0978}, pages = {32 -- 35}, year = {2014}, language = {de} }
