Cross-corrugated triangular channels increase heat transfer in heat exchangers. The mixing effect increases the heat transfer coefficient at the surfaces. In this study, the fluid flow and heat transfer in a triangular corrugated channel are modeled under two constant heat fluxes and different Reynolds numbers. In order to validate, k-ω turbulence model is used. Also, the effect of magnetic fie...

In the present work, the critical heat flux measurements were performed for the subcooled flow boiling of pure water and magnetic nanofluids (i.e., water + 0.01 and 0.1 vol.% Fe‌‌3O4) in a vertical tube. The effect of applying an external magnetic field on the CHF variation was studied experimentally as well. The obtained results indicated that the subcooled flow boiling CHF in the vertical tub...

Major recent advances: Magnetic fluid rheology and flow advances in the past year include: (1) generalization of the magnetization relaxation equation by Shliomis and Felderhof and generalization of the governing ferrohydrodynamic equations by Rosensweig and Felderhof; (2) advances in such biomedical applications as drug delivery, hyperthermia, and magnetic resonance imaging; (3) use of the ant...

The dynamics of some magnetic fluid (MF) samples various concentrations filling the tube horizontally and held by a field axial system made based on unipolar permanent rare-earth ring magnets were studied. an "axial" MSO was studied, as well dependence oscillation frequency length MF cylinder. An original method for determining magnetization is proposed applied to obtained data. Magnetization d...

In this work, e-Fe3N nanoparticles and e-Fe3Nbased magnetic fluid were synthesized by chemical reaction of iron carbonyl and ammonia gas. The size of e-Fe3N nanoparticles was tested by TEM and XRD. Stable e-Fe3Nbased magnetic fluid was prepared by controlling the proper ratio of carrier liquid and surfactant. The saturation magnetization of stable e-Fe3N-based magnetic fluid was calculated acco...
