This relationship can be extended to incl\ide … 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… WebAbstract.
