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 ...
In mobile SCR applications, the most widespread reducing agent is ammonia. However, due to its toxicity it is not stored directly as pressurized or liquefied gas. Instead, an aqueous solution of 32.5 wt % urea is commonly used as ammonia precursor. The ure ...
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 ...

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 ...
One of the challenging problems with autonomous vehicles is their performance at intersections. This paper shows an alternative control method for the coordination of autonomous vehicles at intersections. The proposed approach is grounded in multi-robot co ...
The traditional methodology for estimating vehicle emissions based on vehicle miles traveled and average speed is not reliable because it does not consider the effects of congestion, control devices, and driving mode (cruise, acceleration, deceleration, an ...
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 ...
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 ...
We investigated the millennial variability (1000 A.D.-2000 A.D.) of global biogenic volatile organic compound (BVOC) emissions by using two independent numerical models: The Model of Emissions of Gases and Aerosols from Nature (MEGAN), for isoprene, monote ...
The snowflake (SF) divertor is a plasma configuration that may enable tokamak operation at high performance and lower peak heat loads on the plasma-facing components than a standard single-null divertor. This paper reports on the results of experiments per ...
