Paper Title :
Dam-Break Flow Over Abruptly Contracting Channel

Author :Selahattin Kocaman, Hatice Ozmen-Cagatay

Article Citation :Selahattin Kocaman ,Hatice Ozmen-Cagatay , (2015 ) " Dam-Break Flow Over Abruptly Contracting Channel " , International Journal of Mechanical and Production Engineering (IJMPE) , pp. 73-77, Volume-3,Issue-8

Abstract : Dam-break flow over dry channel with an abrupt contracting part in certain downstream section was investigated. A new experiment was conducted in a smooth-prismatic channel with rectangular cross-section and horizontal bed. The dam-break flow was measured by using digital imaging technique and thus flood wave propagation was sensitively determined. Synchronous filmed images of the dam-break flow were non-intrusively acquired with three cameras, through glass sidewalls of the channel. Free surface profiles were derived directly from the recorded video images without disturbing the flow. The present study focuses on the formation and propagation of the negative bore due to abruptly contracting channel. The measured results were compared with the numerical solution of Reynolds Averaged Navier Stokes (RANS) equations with k-ε turbulence model and good agreement was achieved. Index Terms— Abrupt contraction, dam-break, negative bore, unsteady flow.
