WebRap Summary - CSU Walter Scott, Jr. College of Engineering Turbulentie heeft ook een groot effect op de stabiliteit. Turbulente wervels geven lokaal een grote snelheid bij de steen, waardoor er aan de ene kant wel, en aan de andere kant geen liftkracht is. Hierdoor wordt de steen als het ware uit het bed gewipt. Zie ook de detailopname. In dit voorbeeld ligt de steen op de coördinaat (0,0). Aan de linkerkant is een relatieve snelheid, dus een liftkracht omhoog, aan de rechterkant is geen relatieve snelheid, dus geen liftkracht. Er werkt dus een re…

The stability of granular material in flow can be determined by the Shields formula or the Izbash formula. The first is more suitable for fine grain material (such as sand and gravel), while the Izbash formula is more … Meer weergeven Izbash considered the forces on a stone in the current. These are three active forces and two passive forces. The active forces are the lift force FL, the friction force FS and the drag FD. The passive forces are the weight … Meer weergeven The formula uses the speed near the stone. It is difficult to determine, especially in smooth soils and larger water depths. In these cases, Shields formula is preferable. Meer weergeven Turbulence also has a major effect on stability. Turbulent vortices give locally a high speed at the stone, so on one side there is lift … Meer weergeven Question: What stone size is needed to defend the bottom of a 1 m depth channel at an average flow rate of 2 m/s?
