The coupled dynamics of foam generation and pipe flow

International Journal of Heat and Fluid Flow, 2019
Abstract Foam generation in porous media and foam flow through pipes have been studied extensively to date as uncoupled processes. The coupled dynamics of foam generation and pipe flow, however, are comparatively understudied, despite their importance to industrial applications.

Coupled Non-Equilibrium Processes in Heat Pipes

Journal of Non-Equilibrium Thermodynamics, 1989
A gravity assisted capillary heat pipe is viewed as a direct energy convertor capable of transforming thermal power into hydraulic power, but operating conventionally in the «short-circuit» mode (i.e., no output power). It is demonstrated that the formalism, based on the Onsager Reciprocal Theorem of linear irreversible thermodynamics, developed in ...

Longitudinal Coupling Impedance for a Beam Pipe with a Cavity

IEEE Transactions on Nuclear Science, 1985
A method is presented for the computation of the longitudinal coupling impedance of an azimuthally symmetric obstacle of general shape in a long beam pipe. The method involves a numerical calculation of the fields at mesh points in the cavity alone, from which the additive contribution of the cavity to the coupling impedance of the beam pipe can be ...

Flux Pipe Pads with Improved Coupling Characteristics

2019 16th International Multi-Conference on Systems, Signals & Devices (SSD), 2019
In this paper, flux pipe pad structure is discussed focusing on the analyzing effects of the number of sub-coils and separation between sub-coils on the coupling performance. Simulations show that the flux pipe pads with three or more sub-coils exhibit higher magnetic coupling coefficient as compared to traditional flux-pipe pads with two sub-coils. In

Coupled neutronic, thermal-mechanical and heat pipe analysis of a heat pipe cooled reactor

Nuclear Engineering and Design, 2021
Abstract Heat pipe cooled reactors are solid-state, high temperature reactors with significant thermal expansion which influences the neutronics and thermal analyses. The heat pipe operating conditions determine the heat transfer rates and temperature distribution which then affect the core neutronic and thermal–mechanical behavior, especially during

On the Coupled Extensional–Torsional Response of Flexible Pipes

Volume 3: Pipeline and Riser Technology, 2009
In this paper, the coupled extensional-torsional behavior of a 4″ flexible pipe is studied. The pipe was subjected to pure tension and two different boundary conditions were considered: ends free and prevented from axially rotating. The response of the pipe is predicted with a three-dimensional nonlinear finite element (FE) model.

Fatigue Life Improvement of Threaded Pipe Couplings

ASME 2010 Pressure Vessels and Piping Conference: Volume 5, 2010
In this study it is demonstrated experimentally that the fatigue life of threaded pipe couplings can be improved by providing a more uniform load distribution over the threads of the coupling. The load distribution was changed by applying both global and local stiffness reductions to the coupling.

XLVI.Resonance in coupled pipes

The London, Edinburgh, and Dublin Philosophical Magazine and Journal of Science, 1933
Abstract The natural frequency of a resonator consisting of two coaxial cylindrical pipes of different diameters joined end to end, and closed at the larger end, was investigated theoretically by Aldis. The writer, using a series of such resonators closed at either end, found that the experimental results agreed closely with those obtained by Aldis's ...

Coupling efficiency between light pipes of different dimensions

Applied Optics, 1976
An expression for the transmitted fraction of the uniform and parallel radiation incident upon the coupler between two rectangular light pipes of different physical dimensions is derived. It is a function of the pipe dimension ratio and the angle of the incident radiation.
