Development of the pressure drop model for two-phase flow through a packed bed with small particles
Nihon Kikai Gakkai ronbunshu, 2014 Pressure drop tests of single-phase and two-phase flows through a packed bed with micrometer size diameter particles under laminar upward flow conditions were carried out to develop the new pressure drop model for two-phase flow through a packed bed.

Single- and Two-Phase Flow Characterization Using Optical Fiber Bragg Gratings
Sensors, 2015 Single- and two-phase flow characterization using optical fiber Bragg gratings (FBGs) is presented. The sensor unit consists of the optical fiber Bragg grating positioned transversely to the flow and fixed in the pipe walls.

A two-pressure model for slightly compressible single phase flow in bi-structured porous media [PDF]
, 2012 Problems involving flow in porous media are ubiquitous in many natural and engineered systems. Mathematical modeling of such systems often relies on homogenization of pore-scale equations and macroscale continuum descriptions.

Multiphase Actuation of AC Electrothermal Micropump
Micromachines, 2023 Electrothermal micropumps apply an AC electric field to a conductive fluid within the range of 10 kHz–1 MHz to generate fluid flow. In this frequency range, coulombic forces dominate fluid interactions over opposing dielectric forces, resulting in high ...

Multiscale simulations of porous media flows in flow-based coordinate system [PDF]
, 2008 In this paper, we propose a multiscale technique for the simulation of porous media flows in a flow-based coordinate system. A flow-based coordinate system allows us to simplify the scale interaction and derive the upscaled equations for purely ...

Weyl node with random vector potential [PDF]
, 2016 We study Weyl semimetals in the presence of generic disorder, consisting of a random vector potential as well as a random scalar potential. We derive renormalization group flow equations to second order in the disorder strength.
