PROBABILITY DISTRIBUTION FUNCTION OF NEAR-WALL TURBULENT VELOCITY FLUCTUATIONS被引量:1
《Applied Mathematics and Mechanics(English Edition)》2005年第10期1245-1254,共10页周济福 张强 李家春 
ProjectsupportedbytheNationalNaturalScienceFoundationofChina(Nos.10332050,10572144and10002023)andtheOpeningResearchFoundationoftheStateKeyLaboratoryofWaterResourcesandHydropowerEngineeringScience(No.2003B003)
By large eddy simulation (LES), turbulent databases of channel flows at different Reynolds numbers were established. Then, the probability distribution functions of the streamwise and wall-normal velocity fluctuatio...
