15 sie 2023 · The flow of a two-phase ferrofluid liquid–gas slug under the effect of an external magnetic field is experimentally investigated. The experimental setup is validated using pressure measurements of two-phase gas–liquid slug flows using DI-water and ferrofluid, without an external magnetic field.
1 mar 2020 · The results indicate that the gradient field is especially effective at controlling the gas-liquid contact volume: the foaming of the liquid during the sparging of gas has been completely suppressed by the magnetic forces without any reduction of the mass exchange efficiency.
1 sty 2024 · The utilization of a magnetic field with a strength of 260mT resulted in a significant enhancement of 55% in the maximum power density observed in the parallel flow field fuel cell. Abstract. This study explores the impact of magnetic fields on the operation and performance of proton exchange membrane fuel cells (PEMFCs) with various flow fields.
1 dzień temu · Triggered by the promising applications of PLs in gas separation, PLs are further explored in catalysis particularly to integrate the gas storage and catalytic transformation procedure. This emerging field has demonstrated promising progress to advance catalytic procedures using PLs as catalysts, with performance surpassing that of the pure ...
28 lis 2019 · The shear strength of commercially available MRF varies from 0–100 kPa under the effect of the magnetic field. In valve mode, in the Magnetorheological damper (MR Damper or MRD), the MR fluid flows between two-fixed poles, which are parallel to each other.
11 paź 2023 · Magnetic refrigeration utilizes the magnetocaloric effect of a magnetic material, whose temperature changes according to the change of magnetic field strength.
20 paź 2022 · Magnetic flux leakage (MFL) testing is a widely used nondestructive testing (NDT) method for the inspection of ferromagnetic materials. This review paper presents the basic principles of MFL testing and summarizes the recent advances in MFL. An analytical expression for the leakage magnetic field based on the 3D magnetic dipole model is provided.
