One-form superfluids & magnetohydrodynamics [PDF]

Journal of High Energy Physics, 2020
We use the framework of generalised global symmetries to study various hydrodynamic regimes of hot electromagnetism. We formulate the hydrodynamic theories with an unbroken or a spontaneously broken U(1) one-form symmetry. The latter of these describes a

Relativistic magnetohydrodynamics

Journal of High Energy Physics, 2017
We present the equations of relativistic hydrodynamics coupled to dynamical electromagnetic fields, including the effects of polarization, electric fields, and the derivative expansion.

Polymeric hollow fibers: a modular heat exchanger for thermal management systems of battery modules in electric vehicles [PDF]

EPJ Web of Conferences, 2022
The liquid-cooling system based on polymeric hollow fibers (ø1 mm) embedded inside durable polydicyclopentadiene is proposed for thermal management of li-ion cylindrical batteries from their surface. In the present work, a dramatically improved design is

Contactless Inductive Flow Tomography for Real-Time Control of Electromagnetic Actuators in Metal Casting

Sensors, 2022
Flow control of liquid metals based on the actual flow condition is important in many metallurgical applications. For instance, the liquid steel flow in the mould of a continuous caster strongly influences the product quality. The flow can be modified by

Ultrasound Localization Microscopy in Liquid Metal Flows

Applied Sciences, 2022
Liquid metal convection plays an important role in natural and technical processes. In experimental studies, an instrumentation with a sub-millimeter spatial resolution is required in an opaque fluid to resolve the flow field near the boundary layer ...

Ekman boundary layers in a fluid filled precessing cylinder

AIP Advances, 2021
The fluid flow in a precessing cylinder is investigated numerically with focus on the Ekman boundary layers in the strongly forced regime. Not surprisingly, in that regime, we find deviations from the linear theory due to significant modifications of the

Numerical modeling and experimental validation of the effect of arc distribution on the as-solidified Ti64 ingot in vacuum arc remelting (VAR) process

Journal of Materials Research and Technology, 2022
A numerical model coupling electromagnetic field and plasma arc impact with multiphase transport phenomena such as flow, heat transfer and solidification for the vacuum arc remelting (VAR) process is proposed.

Experimental and Numerical Investigations into Heat Transfer Using a Jet Cooler in High-Pressure Die Casting

Journal of Manufacturing and Materials Processing, 2023
During high-pressure die casting, a significant amount of heat is dissipated via the liquid-cooled channels in the die. The jet cooler, also known as the die insert or bubbler, is one of the most commonly used cooling methods. Nowadays, foundries casting

Laboratory Investigation of Tomography-Controlled Continuous Steel Casting

Sensors, 2022
More than 96% of steel in the world is produced via the method of continuous casting. The flow condition in the mould, where the initial solidification occurs, has a significant impact on the quality of steel products. It is important to have timely, and
