Abstract:
Dam-break flow may cause severe damages on land and population locateddownstream due to flush flooding. In addition to the complexity inherent in dam break flow,existence of buildings changes the rapidly varying flow pattern downstream making theproblem more complex. The way the buildings are oriented and clustered has a great influenceon water depths and velocities of the dam-break flow. To understand the phenomena better, inthis study, the flow around a single building located vertically and excentred with respect tothe main flow direction are investigated experimentally and numerically. The wavepropagation and its interaction with the building was observed using high speed camera andobtained results were compared with FLOW-3D numerical model which uses 3D RANSequations utilizing k - turbulence model. The results were in good agreement.
