Análisis de la influencia del fluido y de las condiciones de movimiento en la respuesta de los amortiguadores magnetoreológicos
Berasategi Arostegi, Joanes (Mondragon Unibertsitatea. Goi Eskola Politeknikoa, 2014)In this thesis the magneto-hydro-dynamic behaviour of magneto-rheological (MR) dampers has been analysed taking into account the damper design, the inner fluid and the applied movement conditions. The thesis is divided in ... -
Aspects Concerning the Fabrication of Magnetorheological Fluids Containing High Magnetization FeCo Nanoparticles
Gómez, Ainara; Berasategi Arostegi, Joanes; Bou-Ali, M. Mounir (MDPI, 2021)Recently, our collaborative work in the fabrication of a magnetorheological fluid (MRF) containing high magnetization FeCo nanoparticles (NPs, fabricated in our laboratories using the chemical reduction technique; MS = 212 ... -
Effect of liner thermal properties and liner pre-cooling on the thermal management of fast-filling of hydrogen tanks
Blanco-Aguilera, Ricardo; Martinez Agirre, Manex; Berasategi Arostegi, Joanes; Penalba, Markel; Bou-Ali, M. Mounir; Shevtsova, Valentina (Elsevier, 2024)In transportation applications, filling high pressurised hydrogen tanks within a few minutes implies a fast and large temperature increase that can compromise the structural integrity of the storage system and the safety ... -
Fe nanoparticles produced by electric explosion of wire for new generation of magneto-rheological fluids
Berasategi Arostegi, Joanes; Gómez, Ainara; Bou-Ali, M. Mounir (IOP Publishing, 2018)Iron magnetic nanoparticles were produced by the technique of the electric explosion of a wire (EEW). The major crystalline phase (95 ± 1%) was α-Fe with lattice parameter a = 0.2863(3) nm. The size of the coherent diffraction ... -

High magnetization FeCo nanoparticles for magnetorheological fluids with enhanced response
Gómez, Ainara; Berasategi Arostegi, Joanes; Bou-Ali, M. Mounir (Royal Society of Chemistry, 2021)We present results concerning the fabrication of a new magnetorheological fluid with FeCo magnetic nanoparticles (NPs) as magnetic fillers. These NPs have been fabricated by using the chemical reduction technique and show ... -
Influence of nanoparticles morphology in magnetic fluids
Gómez, Ainara; Berasategi Arostegi, Joanes; Bou-Ali, M. Mounir (Elsevier, 2024)In this work magnetic fluids at two different volume concentrations (5 % and 10 %) of magnetite nanoparticles of different morphologies and sizes (octahedral, 38 ± 5 nm; truncated octahedral, 10 ± 1 nm; rod-like, 95 nm x ... -
A novel direct liquid cooling strategy for electric vehicles focused on pouch type battery cells
Fernandez de Arroiabe, Peru; Martinez Agirre, Manex; Berasategi Arostegi, Joanes (Elsevier Ltd., 2022)In this work, a novel direct liquid cooling strategy for a large-scale lithium-ion pouch type cell is proposed to control the cell working temperature within the optimum range of performance and safety. With a modular ... -
Parametric Optimisation of a Direct Liquid Cooling–Based Prototype for Electric Vehicles Focused on Pouch-Type Battery Cells
Martinez Agirre, Manex; Fernandez de Arroiabe, Peru; Berasategi Arostegi, Joanes (MDPI, 2022)In this work, a numerical optimisation process is applied to improve the fluid dynamical aspect of an innovative direct liquid cooling strategy for lithium-ion–based HEV/EV. First, the thermofluidic numerical model of the ... -
