80 K cryogenic stage for ice lithography

Danick Briand, Rubaiyet Iftekharul Haque, Jaemin Kim

We present a cryogenic system design and development for ice lithography. The cryo-stage is designed with embedded channels to allow direct liquid nitrogen flow, enabling fast cryogenic cooling, and low sample temperature. The stage cools down to 78.8 K in ...

Customized Neural Network training to predict the highly imbalanced data of domestic hot water usage

Dolaana Khovalyg, Amirreza Heidari

Despite space heating and cooling, the energy use for hot water production has not changed significantly over time and accounts for a big share in modern, well-insulated buildings. The main challenge of hot water generation lies in the highly stochastic na ...

Microchannel cooling for the LHCb VELO Upgrade I

Alessandro Mapelli, Giulia Romagnoli, Victor Coco

The LHCb VELO Upgrade I, currently being installed for the 2022 start of LHC Run 3, uses silicon microchannel coolers with internally circulating bi-phase CO2 for thermal control of hybrid pixel modules operating in vacuum. This is the largest scale applic ...

Convective regimes induced by surface cooling and topography in stratified waterbodies

Damien Bouffard, Tomy Doda, Hugo Nicolás Ulloa Sánchez, 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 ...

Reaching Thermal Comfort Zone Limits for Resilient Building Operation: A Winter Case Study for Offices

Dolaana Khovalyg, Verena Marie Barthelmes, Arnab Chatterjee

A specific range of acceptable indoor thermal conditions is stipulated by building performance standards to assure minimum dissatisfaction of occupants. Thus, the operation of buildings in practice tends to follow a cautious approach by setting the indoor ...

Seasonality 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 ...
