the developing turbulent flow in an open channel is a complex three-dimensional flow influenced by the secondary currents and free surface effects and is, therefore, not amenable to analytical solution. this paper aims to study the impact of three key hydraulic parameters (relative roughness, the froude number and the reynolds number) on the establishment length using computational fluid dynami...

in this paper, the flow of couple stress fluid is investigated in a helical screw rheometer (hsr). by unwrapping the channel, lands, and the outside rotating barrel, the geometry of hsr is approximated as a shallow infinite channel. both one- and two-dimensional analysis of the problem is presented using rectangular coordinates. in either case an exact solution of the flow problem is presented ...

Wireless communication in confined metal environment such as rectangular metal cavity has attracted more and more attentions recently. The channel characteristics in such an environment are different from those in the traditional wireless communication environments: extremely rich multipath components make communication very challenging. Multiple input multiple output (MIMO) plus ultra-wideband...
