Progress in Experimental and Theoretical Evaluation Methods for Textile Permeability

simulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water

abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...

Experimental and theoretical progress in pipe flow transition.

There have been many investigations of the stability of Hagen-Poiseuille flow in the 125 years since Osborne Reynolds' famous experiments on the transition to turbulence in a pipe, and yet the pipe problem remains the focus of attention of much research. Here, we discuss recent results from experimental and numerical investigations obtained in this new century. Progress has been made on three f...

Computation of Permeability of Textile with Experimental Validation for Monofilament and Non Crimp Fabrics

For the manufacturing of composite materials with textile reinforcement, the permeability of the textile is a key characteristic. Using the law of Darcy, permeability can be derived from a numerical simulation of the fluid flow, i.e. by solving the Navier-Stokes or Brinkman equations. In this paper we present the results of simulations with two different flow solvers: a finite difference Navier...

Theoretical and Experimental Performance Evaluation Methods for DD-OFDM Systems with Optical Amplification

— Several methods have been proposed to evaluate theoretically and experimentally the performance of optically amplified direct-detection orthogonal frequency division multiplexing systems. In this paper, we review those methods, and highlight their main advantages and disadvantages.
