Energy Integration On Multi-Periods For Vehicle Thermal Powertrains

François Maréchal, Zlatina Kirilova Dimitrova

Internal combustion engines are the most applied energy converters in passenger cars. In order to increase their efficiency, energy integration techniques are used to recover waste heat. An adapted methodology is required to design the organic Rankine cycl ...

In-building waste water heat recovery: urban-scale methods for the characterisation of water streams and the assessment of energy savings and costs

François Maréchal, Alexandre Suzanne Jean-Marie Bertrand, Riad Aggoune

Residential domestic hot water (DHW) energy consumption represented 16% of the EU household heating demand in 2013. With the improvement of the building envelop, DHW contribution to energy consumption is expected to increase signi cantly, with values betwe ...

Combined Exergy Analysis and Energy Integration for the Optimization of Nitrogen Fertilizer Plants

François Maréchal, Daniel Alexander Florez Orrego, Shivom Sharma

Modern ammonia production plants are equipped with efficient energy integration networks able to recover an important fraction of the enthalpy of reaction released by the exothermic chemical systems. However, to fully supply the exergy demands of the highl ...

Replicated microcellular aluminium structures for thermal management

Alexandros Athanasiou-Ioannou

Open-pore aluminium foams are of interest in thermal management of power electronics due to their large specific surface area, low weight and relatively high thermal conductivity. The replication process is a low-cost and simple foam manufacturing method t ...

Simultaneous synthesis of non-isothermal water networks integrated with process streams

François Maréchal, Maziar Kermani

This paper is an extension of our previous study [1] and addresses simultaneous synthesis of nonisothermal water networks heat-integrated with hot and cold process streams. Hence, the scope of heat integration is expanded by enabling heat integration of pr ...

Waste heat valorisation at multiple scales

Alexandre Suzanne Jean-Marie Bertrand

Considering current environmental issues (e.g. climate change, air pollution) related to energy consumption, this thesis focuses on data characterisation and integrated optimisation methods for waste heat valorisation at the building, city and regional sca ...

Channel-to-channel heat flux variation in compact minichannel heat exchangers due to the effect of louvered fins

A typical minichannel evaporator used in AC&R applications is made of stacked parallel aluminum extruded multiport plates and louvered fins placed between them. In this configuration cold refrigerant flows inside the ports, and hot air passes though the lo ...

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 ...
