A geometrical method for computing the distribution of boundary shear stress across irregular straight open channel
A method called Merged Perpendicular Method (M.P.M.)has been developed to compute the distribution of boundary shear stress across irregular straight channels. In a concave angle of a cross section, computed shear stress is lower than in a convex...
Disscussion : A geometrical method for computing the distribution of boundary shear stress across irregular straight open channel
The boundary shear stress is one of the most important parameters both for practical developments and for fundamental studies in open channel hydraulics and fluid mechanics. The authors have presented a fairly reliable method to assess the boundary...
FLOW PATTERNS AND WALL SHEAR STRESS DISTRIBUTION IN HUMAN VERTEBROBASILAR SYSTEM: A COMPUTATIONAL STUDY TO INVESTIGATE SMOKING EFFECTS ON ATHEROSCLEROTIC STENOSIS AT DIFFERENT AGES
The blockage of arteries in the human vertebrobasilar system (VBS) usually results in major disability or death. It has been widely seen that atherosclerotic stenosis occurs at locations with a low wall shear stress or a high oscillatory shear index...
The regularity of wind induced sediment resuspension in Meiliang Bay of Lake Taihu
Experimental Study of Wastewater Effect on the Deposition of Cohesive Sediment
In this study, the characteristics of sediment deposition with three levels of wastewater, different shear stress and initial sediment concentration were investigated in an annular flume. Sediment used for experiments was taken from Pirbalut dam...
THE INFLUENCE OF STENT GEOMETRY AND NON-NEWTONIAN EFFECT ON HEMODYNAMICS IN STENTED CORONORY ARTERY
blood rheology. The results show that streamlined stents prevent low and high wall shear stresses in the vicinity of the stent. Also, these stents decrease the risk of thrombosis and restenosis by eliminating the particle residence time in the region...
Comparison between 5 methods to calculate boundary shear stress distribution in open channel
In 1999, Merged Perpendicular Method (MPM) was developed by Khodashenas & Paquier in order to compute the distribution of boundary shear stress across irregular straight channels. For examination and validation of MPM, 4 methods are studied...
River bed deformation calculated from boundary shear stress
Deformation of various kinds of cross-sections was computed with the hypothesis that scour or deposit were directly related to shear stress computed by the Merged Perpendicular Method. Final stabilised cross section agrees with theoretical stable...
