Convective regimes induced by surface cooling and topography in stratified waterbodies
Damien Bouffard, Hugo Nicolás Ulloa Sánchez, Tomy Doda, Cintia Luz Ramon Casanas
Gravitational convection plays a significant role in the ventilation, heat and mass distribution of aquatic systems. This study investigates thermally driven convection resulting from heat loss at the air-water interface during cooling periods in freshwate ...
Madrid2022Seasonality of density currents induced by differential cooling
Alfred Johny Wüest, Damien Bouffard, Hugo Nicolás Ulloa Sánchez, Tomy Doda
When lakes experience surface cooling, the shallow littoral region cools faster than the deep pelagic waters. The lateral density gradient resulting from this differential cooling can trigger a cold downslope density current that intrudes at the base of th ...
2022Two novel cogeneration charging stations for electric vehicles: Energy, exergy, economic, environment, and dynamic characterizations
Jan Van Herle, Hossein Pourrahmani, Chengzhang Xu
This paper suggests two novel designs for the electric vehicle charging stations using LiMn2O4 Lithium-ion battery and based on a Solid Oxide Fuel Cell (SOFC) and absorption refrigeration cycle (ARC) technologies to provide electricity and cooling, respect ...
PERGAMON-ELSEVIER SCIENCE LTD2022EFFICIENT COOLING SYSTEM FOR SUPERCONDUCTING GANTRY MAGNET
Superconductors are used in high-energy physics to generate large magnetic fields. The flowing current is progressively increased to its nominal value to achieve the target magnetic field. During the ramp-up progress, the varying magnetic field induces Edd ...
2022Local heating and cooling effectiveness - an evaluation method based on calculated local and overall thermal state
Dolaana Khovalyg, Mohamad Rida
The application of Personal Comfort Systems (PCS) in the buildings demonstrated their potential to improve thermal comfort and reduce energy use by the space conditioning HVAC systems. With its personal controllability (on-demand) PCS is a practical soluti ...
TU Delft2022Competition between cooling and shortwave radiation in shaping near-surface convection in pelagic waters of Lake Geneva
When lake surface waters above the temperature of maximum density 4◦C cools, the verysurface fluid parcels become denser than their neighbours below. The latter process leads to a gravitationally unstable density distribution which may trigger ‘free convec ...
2021Development of overturning circulation in sloping waterbodies due to surface cooling
Alfred Johny Wüest, Damien Bouffard, Hugo Nicolás Ulloa Sánchez, Tomy Doda, Cintia Luz Ramon Casanas
Cooling the surface of freshwater bodies, whose temperatures are above the temperature of maximum density, can generate differential cooling between shallow and deep regions. When surface cooling occurs over a long enough period, the thermally induced cros ...
CAMBRIDGE UNIV PRESS2021Improved Natural-Air-Convection-Cooling Formulas for Medium Frequency Transformer Design Optimization
Drazen Dujic, Marko Mogorovic, Jonas Piet K Le Roy
This paper provides accurate analytic models for a computationally efficient estimation of the natural con- vection cooling coefficients for typical geometries, such as those encountered in transformers. Proper thermal coordination is an essential step of ...
2021Hybrid Two-Phase Cooling Technology For Next-Generation Servers: Thermal Performance Analysis
John Richard Thome, Jackson Braz Marcinichen, Raffaele Luca Amalfi, Filippo Cataldo
This paper advances the work presented at ITHERM 2020 where a novel passive two-phase technology was introduced for more efficient cooling of datacenters compared to air-based cooling solutions (e.g. In-Room, In-Row, etc.). The proposed hybrid two-phase co ...
