De Gunst, M. (author)Het onderwerp van deze studie is een niet-uniforme stroming waarin sprake is van een plaatselijk verhoogde aanval op het bodemmateriaal door de lokaal hogere turbulentie. In een 15 m lange stroomgoot met een breedte van 40 cm is door middel van een backward-facing step ofwel afstap een niet-uniforme stroming gecreeerd. Om de schade aan de...master thesis 1999

Van Prooijen, B.C. (author)Dit afstudeerwerk bestaat uit het ontwerpen van een fysisch model, het uitvoeren van experimenten, het verwerken van de metingen en het interpreteren van de resultaten. Allereerst wordt in hoofdstuk 2 aan de hand van een probleemanalyse ingegaan op de literatuur betreffende de (ondiepe) menglaagstroming en wordt de doelstelling van het...master thesis 1999

Kranenburg, C. (author)The Prandtl mixing-length model of turbulent exchange of mass and momentum is applied to calculate the entrainment of overlying water into a layer of suspended fine sediment at a horizontal bed. In the field the flow and turbulence in such a concentrated benthic suspension (CBS) are driven by a streamwise pressure gradient resulting from the...report 1999

Runge, A.C. (author)De concentratie van het opgezogen zandwatermengsel en de mate van turbulentie in het beun van een sleephopperzuiger zijn van grote invloed op de snelheid van bezinken van het zandwatermengsel in het beun. Om de kennis van deze invloedsfactoren op de snelheid van bezinken te vergroten is een proefopstelling gebouwd waarin de bezinking van...master thesis 1999

Westin, K.J.A. (author), Henkes, R.A.W.M. (author)Boundary layer transition induced by high levels of free stream turbulence (FSl), so called bypass transition, can not be predicted with conventional stability calculations (e.g. the en-method). The use of turbulence models for transition prediction has shown some success for this type of flows, and the present study is a further investigation...book 1998

Henkes, R.A.W.M. (author)An overview is given on the background of different turbulence models that can be used to compute boundary layers in external aerodynamics, such as for aircraft. The overview includes algebraic models (Cebeci-Smith, Baldwin-Lomax), a half-equation model (Johnson-King), two-equation models ( K-E-K-), and a differential Reynolds-stress model. The...book 1998

Suastika, I.K. (author)In this report we present some results of a laboratory pilot study which has been conducted to test a method to artificially enhance the turbulence of a water flow in a laboratory flume. The purpose of this test is to provide data which will be used to verify whether the method is suitable for the study of the dissipative effects of turbulence...report 1998

Bijvelds, M.D.J.P. (author)In this report the water flow in harbours, that are situated on a river, are considered. Due to the flow velocity difference between the river and the harbour, a turbulent mixing layer develops at the harbour entrance. The shallowness of the water induces the coexistance of two disparate turbulent length scales in these regions. Besides the ...report 1997

Van der Wegen, M. (author)A shallow water mixing layer is a flow pattern which develops between two adjacent streams with a different velocity. The horizontal dimensions of a shallow water mixing layer are much larger than the depth. This results in a turbulent process in the mixing layer which is characterized by the presumable presence of two distinct turbulent length...master thesis 1996
