Merging Flow in Co-Axial Cylindrical Pipes

Effect Of Electric Field On Liquid Viscosity in Co-Axial Cylindric Pipes

Axial segregation in a cylindrical centrifuge.

We propose a theory for axial segregation of suspensions of non-neutrally buoyant particles in a rotating cylinder. The cylinder is oriented in the horizontal plane, so that any axial forces must arise from interparticle interactions. We show that the hydrodynamic interaction between pairs of particles produces a relative motion in the axial direction, independent of the gravitational force. If...

Coupling between two cylindrical light pipes: a design.

An expression for the transmission characteristics of a conical coupling is derived. This expression is shown to be useful for choosing an optimum coupling length.

3D ICs-power Analysis Using Cylindrical and Co-axial Through Silicon Via (TSV)

In this study, analytical model and electrical equivalent circuit of Through Silicon Via (TSV) is analyzed. Through silicon Vias form an integral component of the 3-D IC technology by enabling vertical interconnections in 3-D ICs. Among various types, the performances of the simplified lumped TSV model of cylindrical and co-axial type were studied. The performance analyses of these structures w...

Turbulent flow in smooth and rough pipes.

Recent experiments at Princeton University have revealed aspects of smooth pipe flow behaviour that suggest a more complex scaling than previously noted. In particular, the pressure gradient results yield a new friction factor relationship for smooth pipes, and the velocity profiles indicate the presence of a power-law region near the wall and, for Reynolds numbers greater than about 400x103 (R...
