Forced hydraulic jump on non-protruding rough beds
Tokyay, Nuray; Simsek, C. (2011-10-01)
Baffle blocks and sills are commonly used to stabilize the location of a hydraulic jump and shorten its length. However, corrugations or prismatic roughness elements may be effective alternatives to them. In the present study, experiments were performed to determine the effects of corrugations and prismatic roughness elements on fundamental characteristics of jump such as length, tailwater depth, and energy dissipation capacity. Corrugations were placed to cover the entire length of the basin. Prismatic rou...
Helicopter lobed nozzle optimization with differential evolution method
Bayat, Akay; Perçin, Mustafa; Department of Aerospace Engineering (2021-2-11)
The main purpose of this study is to develop a methodology for the optimization of an ejector system geometry that is used for the helicopter engine bay cooling. The performance of an ejector system is directly related to the entrainment ratio, which is the ratio of the secondary flow rate to the primary flow rate, and the turbine exit backpressure. In the literature, it is observed that the nozzle geometry used in the ejector system has a significant effect on the performance and that the most efficient ge...
Hydraulic adjustments of the Bosphorus exchange flow
Oguz, T (American Geophysical Union (AGU), 2005-03-19)
A three dimensional model elucidates connection between observed internal hydraulic characteristics of the Bosphorus flow and channel configuration. A typical two-layer, quasi-steady exchange flow system is shown to be hydraulically adjusted within the strait by a series of morphological features. Three successive hydraulic controls occur within the southern 10 km zone: first near the southern exit due to convex bending of the channel, then at the southern sill and at the constriction. Finally, the exchange...
Hydraulic characteristics of modified tyrolean type intakes
Yılmaz, Kuta; Göğüş, Mustafa; Department of Civil Engineering (2019)
Today, besides the dams, construction of runoff-river type hydroelectric power plants are also important for producing the required electricity. Among the runoff-river hydroelectric power plants, Tyrolean type intakes are very popular as they do not need reservoirs. These intakes are mostly constructed on rivers which carry sediment and have large slopes. The inclination angle of the rack, θ, rack length, L, and the rack spacing, e, are the most important parameters that determine the amount of sediment tha...
