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

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

Magnetohydrodynamics as Superfluidity [PDF]
Physical Review Letters, 2019 We show that relativistic magnetohydrodynamics (MHD) can be recast as a novel theory of superfluidity. This new theory formulates MHD just in terms of conservation equations, including dissipative effects, by introducing appropriate variables such as a magnetic scalar potential, and providing necessary and sufficient conditions to obtain equilibrium ...

Dynamo Action in Magnetohydrodynamics and Hall‐Magnetohydrodynamics [PDF]
The Astrophysical Journal, 2003 The first direct numerical simulations of turbulent Hall dynamos are presented. The evolution of an initially weak and small-scale magnetic field in a system maintained in a stationary regime of hydrodynamic turbulence (by a stirring force at a macroscopic scale) is studied to explore the conditions for exponential growth of the magnetic energy.

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

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

On the magnetohydrodynamic load and the magnetohydrodynamic metage [PDF]
Physics of Plasmas, 2008 In analogy with the load and the metage in hydrodynamics, this paper defines magnetohydrodynamic load and magnetohydrodynamic metage in the case of magnetofluids. They can be used to write the magnetic field in MHD in Clebsch’s form. It has been shown herein how these two concepts can be utilized to derive the magnetic analog of the Ertel’s theorem and

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
