Local and Global Friction Factor in a Channel with V-Shaped Bottom

This paper presents an experimental research on the distribution of local friction factor, fb, and global friction factor, f, over the cross-section of a channel with V-shaped bottom, which typically occurs in sewers and culverts. Several series of experiments were conducted for measuring velocity and boundary shear stress. It is found that, Darcy-Weisbach, f, is more sensitive than other resis...

A Comprehensive Model for Stiffness Coefficients in V-Shaped Cantilevers

   During past decade the AFM based nanomanipulation has been focus of attention as the promising nano fabrication approach. The main challenge in this process is the real-time monitoring. Consequently, the dynamic models have been proposed as a solution to the existing challenge. In the modeling approach the magnitudes of the forces are proportional to the stiffness coefficients o...

Fluid Flow over a Sharp and Blunt V-shaped Region

Tok tekutiny ostro lomeným potrubím v tvare V In this paper we study a viscous fluid flow over a V-shaped body for a range of Reynold's number from Re = 5 up to Re = 500. We solved the unsteady Naveir-stokes equations in the stream function vorticity formulation. The irregular physical domain is transformed into a rectangular shape using the elliptic grid generation. We applied the Finite difer...

Mathematical Modeling of Flow in a Granular Permeable Bed Channel

In this research, a two-dimensional mathematical model using  turbulence model was developed in a rectangular channel with granular permeable bed. Finite volume method was used for numerical solution of governing equations. The equations considered are discretized using Hybrid difference scheme while applying SIMPLE algorithm to correct velocity components in the continuity equation. In the dev...
