Dynamic Thermal Performance of the BIPV Facades

Building-integrated photovoltaics (BIPV), generally integrated on the roofs, are more and more often installed on the facade as a result of a growing need in renewable energy generating surfaces. This allows maximizing the use of the building surfaces to g ...

Detailed hydrodynamics of cold density currents generated by differential cooling along the sloping bed of Lake Geneva

David Andrew Barry, Ulrich Lemmin, François Mettra, Rafael Sebastian Reiss

Deep water ventilation and mixing are of great importance for large lake ecosystems. Relevant processes include cold density currents due to differential cooling, inter-basin exchange and upwelling. At present, a good understanding of these processes in la ...

Operational Map And Thermal Performance Of A Thermosyphon Cooling System For Compact Servers

John Richard Thome, Jackson Braz Marcinichen, Raffaele Luca Amalfi, Filippo Cataldo

This paper advances the state-of-the-art in novel passive two-phase systems for more efficient cooling of datacenters and telecom central offices compared to the traditional air-based cooling solutions (e.g. aisle-based containment systems). The proposed p ...

Pile interaction effects and environmental impacts of refrigerant on the performance of an energy pile foundation

Selina Heiniger, Annik Julia Schaufelberger

Energy piles are an efficient renewable energy source. The advantage of these heat capacity systems is the use of already necessary infrastructure for structural support to extract heat from the ground. In this project a numerical finite element model of t ...

Hybrid 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 ...

Machine learning enhancement of thermal response tests for geothermal potential evaluations at site and regional scales

Lyesse Laloui, Alessandro Francesco Rotta Loria

This study explores and validates a machine learning approach for the practical, effective, and precise prediction of the thermo-physical characteristics that are essential for the analysis and design of shallow geothermal systems, including borehole heat ...

Serial dependence under memory load

Michael Herzog, David Pascucci, Ayberk Ozkirli, Gizay Ceylan, Yury Markov, Natalia Tiurina

Perceptual decisions are biased towards previous stimuli, a phenomenon known as serial dependence. However, the mechanisms of this bias are unknown. For example, it is debated whether serial dependence reflects a perceptual bias or interference of prior st ...

Approaching detachment in I-mode-response of core confinement and the edge pedestal in the ASDEX Upgrade tokamak

Antoine Pierre Emmanuel Alexis Merle

Experiments on nitrogen assisted divertor detachment in the improved energy confinement mode (I-mode) are reported from the ASDEX Upgrade tokamak. When nitrogen is introduced into the divertor and radiation losses cool the divertor plasma down, a loss of c ...

Impact of air-flow on thermal performance of air-spaces behind cladding (ASHRAE 1759-TRP)

Dolaana Khovalyg, Mohammad Rahiminejad

The project ASHRAE 1759-RP addresses the impact of the ventilated cavity behind external claddings on the thermal performance of the wall structure by defining “effective thermal resistance” of air gaps based on the linearized network of thermal resistance ...
