Thermo-Economic Modelling and Process Integration of CO2-Mitigation Options on Oil and Gas Platforms

François Maréchal, Tuong-Van Nguyen, Laurence Tock

The offshore extraction of oil and gas is an energy-intensive process associated with large CO2 and CH4 emissions to the atmosphere and chemicals to the sea. The taxation of these emissions has encouraged the development of more energy-efficient and enviro ...

Impact of Operating Regime on Aviation Engine Emissions: Modeling Study

Pénélope Leyland

This work is focused on the numerical analysis of pollutant formation in an aviation gas turbine engine at different values of power setting. The analysis is conducted on the basis of a comprehensive approach treating the reactor net model for description ...

Impact of different light intermittence regimes on bacteria during simulated solar treatment of secondary effluent: Implications of the inserted dark periods

César Pulgarin, Stefanos Giannakis

In this study, the effect of light intermittence on solar disinfection of secondary treated wastewater was investigated. Synthetic secondary effluent was spiked with Escherichia coli and submitted to 3 different light intermittence regimes by circulating t ...

Boundary control and shape optimization for the robust design of bypass anastomoses under uncertainty

Alfio Quarteroni, Gianluigi Rozza, Andrea Manzoni, Toni Mikael Lassila

We review the optimal design of an arterial bypass graft following either a (i) boundary optimal control approach, or a (ii) shape optimization formulation. The main focus is quantifying and treating the uncertainty in the residual flow when the hosting ar ...

Thermo-mechanical fatigue behaviour of welded tubular parts made of ferritic stainless steel

Roland Logé

Car exhaust manifolds are critical components subjected to cyclic thermo-mechanical fatigue (TMF) during function. To reduce design costs, robust numerical design tools are required to assess their behaviour and lifetime. Manifolds are constructed by weldi ...

Self-consistent simulation of plasma scenarios for ITER using a combination of 1.5D transport codes and free-boundary equilibrium codes

Jonathan Bryan Lister, Javier García Hernández, Karim Besseghir

Self-consistent transport simulation of ITER scenarios is a very important tool for the exploration of the operational space and for scenario optimization. It also provides an assessment of the compatibility of developed scenarios (which include fast trans ...

Thermo-economic analysis and modeling of oxyfuel processes

Within the goal of reducing the atmospheric CO2 emissions, CO2 capture and storage (CCS) is regarded as a promising option. For CO2 capture different concepts are investigated; post-combustion, pre-combustion and oxyfuel-combustion (pure O2 oxidation). Her ...

Polymer spiral film gas-liquid heat exchanger for waste heat recovery in exhaust gases

Antoine Breton

In this master thesis report the development of an innovative spiral heat exchanger based on polymer materials is described. Building prototypes, erection of a test bench and firsts tests of the heat exchanger are presented. The heat exchanger prototype su ...

Optimal open-loop control of the recirculation length in the wake of a cylinder

François Gallaire, Edouard Boujo

We consider steady equilibrium solution of the 2-D Navier-Stokes equations describing the flow around a circular cylinder. It is well known that, for moderate Reynolds numbers, the recirculation length is an increasing function of the Reynolds number. We f ...

Technologies for gas turbine power generation with CO2 mitigation

François Maréchal

A review of the state of the art gas turbine power plants designs with CO2 capture was performed to set up a list of technologies to be considered in a conceptual process superstructure. It has been found that the efficiency and economics of carbon dioxide ...
