A Phase-Field Method for Interface-Tracking Simulation of Two-Phase Flows [PDF]

Progress in Multiphase Flow Research, 2005
For interface-tracking simulation of two-phase flows, we propose a new computational method, NS-PFM, combining Navier-Stokes (NS) equations with phase-field model (PFM). Based on the free energy theory, PFM describes an interface as a volumetric zone across which physical properties vary continuously.

Thermal two-phase flow with a phase-field method [PDF]

International Journal of Multiphase Flow, 2018
Abstract Phase field methods have become of great interest for the simulation of droplet and bubble dynamics, moving free interfaces and more recently phase change phenomena. One example is the Navier–Stokes–Korteweg (NSK) equations. With a particular focus on the van der Waals fluid, we present the numerical solution of the NSK system with the ...

Simulation of Dendritic-Eutectic Growth with the Phase-Field Method

Acta Materialia, 2023
Solidification is an important process in many alloy processing routes. The solidified microstructure of alloys is usually made up of dendrites, eutectics or a combination of both. The evolving morphologies are largely determined by the solidification process and thus many materials properties are dependent on the processing conditions.

Analysis and design of a two-speed single-phase induction motor with 2 and 18 pole special windings [PDF]

, 2005
The motor presented employs multiple independent windings for operation with two very different pole numbers. The 18-pole field is produced with a symmetrical three-phase winding connected in a Steinmetz arrangement to a single-phase supply.

Therapeutic Apheresis in Nigeria: A Multi‐Center Summary of Abstracts From the Inaugural Nigerian Society for Apheresis Scientific Meeting

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Therapeutic apheresis (TA) is an established treatment modality for hematologic, neurologic, and immunologic disorders, yet access remains severely limited in sub‐Saharan Africa. Donor apheresis, including platelet apheresis collection from healthy donors, represents an important complementary modality supporting blood product ...
