Modeling and assessment of high-temperature photo-electrochemical devices

In this thesis, the feasibility and performance of photo-driven electrochemical (PEC) devices working at elevated temperatures (T>700 K) is investigated and modeled. In such high-temperature PEC devices, a part of the solar spectrum is used for generating ...

Thermodynamic analysis of a tri-generation system using SOFC and HDH desalination unit

Jan Van Herle, Hossein Pourrahmani

The lack of freshwater in many countries pushes authorities to utilize desalination units. Solid Oxide Fuel Cells (SOFC) have shown promising results to provide the power to establish a multi-generation system using hydrogen as a renewable source. In this ...

Dynamic response of a compressible binary fluid mixture

Binary fluids are present in a wide variety of systems at microscales, such as microfluidic devices containing drops, fluids with air bubbles trapped in them, and devices designed to mix fluids or to make two fluid substances react. Microfluidics devices a ...

Extension of Winkler’s solution to non-isothermal conditions for capturing the behaviour of plane geostructures subjected to thermal and mechanical actions

Lyesse Laloui, Qazim Llabjani, Alessandro Francesco Rotta Loria, Jacopo Zannin

Before this study, no analytical models had been made available for describing the behaviour of plane geostructures subjected to thermal and mechanical actions. This knowledge gap notably represented a limitation for investigations about the behaviour of s ...

Multi-criteria optimization of a renewable hydrogen and freshwater production system using HDH desalination unit and thermoelectric generator

Hossein Pourrahmani

This article presents the exergoeconomic evaluation of a new geothermal-based integrated system, which produces hydrogen and freshwater. The proton exchange membrane electrolyzer (PEME) and humidifier-dehumidifier (HDH) units are responsible for hydrogen a ...

Small-scale organic Rankine cycle turbo-generator for waste heat recovery on truck engine

Kévin Rosset

Truck engine waste heat recovery (WHR) systems have been investigated for many years. Among them, organic Rankine cycle (ORC) systems show the highest potential, but still lack efficient small-scale expansion devices, in practice. Proposed expanders are of ...

Exergy assessment and techno-economic optimization of bioethanol production routes

François Maréchal

Currently, electricity generation and second-generation ethanol production from lignocellulosic feedstocks represent technological alternatives in the bioenergy sector. Nevertheless, the introduction of new production processes denotes a real challenge due ...

Equivalent pier analysis of full-scale pile groups subjected to mechanical and thermal loads

Lyesse Laloui, Alessandro Francesco Rotta Loria

This study presents an equivalent pier analysis of the vertical deformation and displacement of full-scale pile groups subjected to mechanical and thermal loads that are associated with a structural support and a geothermal heat exchanger operation, respec ...

Thermo-economic analysis of transcritical CO2 cycles with bounded and unbounded reheats in low-temperature heat recovery applications

Ali Amini

Performance of transcritical CO2 Rankine cycles with and without reheat process is investigated thermo-economically in low-grade waste heat recovery applications. Two reheating scenarios are proposed to evaluate the effect of bounded and unbounded reheats ...

Tip asymptotic of a hydraulic fracture driven by a power law fluid accounting for the presence of a fluid lag

Brice Tanguy Alphonse Lecampion, Fatima-Ezzahra Moukhtari

We investigate the tip region of a hydraulic fracture driven by a power law fluid propagating at a constant velocity in an impermeable linear elastic isotropic medium. We account for the presence of a fluid lag of a priori unknown length at the tip of the ...
