Ground temperature modelling: The case study of Rue des Maraîchers in Geneva

Jean-Louis Scartezzini, Jérôme Henri Kämpf, Govinda Upadhyay

This paper presents a methodology to approximate the urban heat island effect by using a PostgreSQL database and CitySim software, a simulation tool to evaluate urban energy flows. A ground temperature model has been developed for shallow depths (until 4m) ...

Toward the determination of joint volatility-hygroscopicity distributions: Development and response characterization for single-component aerosol

Athanasios Nenes

This work presents the development and characterization of a thermodenuder for the study and interpretation of aerosol volatility. Thermodenuder measurements are further combined with a continuous-flow streamwise thermal gradient CCN counter to obtain the ...

Numerical study of the heating-cooling effects on the geotechnical behaviour of energy piles.

Lyesse Laloui, Fabrice Dupray, Alice Di Donna

Energy geostructures represent a renewable and clean source of energy which can be used for heating and cooling of buildings and de-icing of infrastructures. This technology couples the structural role of geostructures with the energy supply, using the pri ...

Radiation-Ablation Coupling for Capsule Reentry Heating via Simulation and Expansion Tube Investigations

Pénélope Leyland, Umar Sheikh, Daniel Potter, Ojas Joshi, Nikhil Banerji, Jérémy Raphaël Mora-Monteros, Valentin Marguet, Elise Joy Fahy

A capsule entering a planetary atmosphere at hypersonic speeds experiences high levels of radiative heating. Furthermore, coupling between the ablation products from the surface of the vehicle and the high temperature gas can have a major effect on the hea ...

On Using Tunnel Anchors and Bolts as Heat Exchangers with the Ground

Lyesse Laloui, Fabrice Dupray, Thomas Mimouni

Heating and cooling of the buildings represent an important area of energy consumption in the developed countries. Furthermore, a large part of this demand is still satisfied with fossil resources such as oil or gas. Therefore, developing alternative and r ...
