Multi-Fidelity Design Optimisation of a Solenoid-Driven Linear Compressor Vrije Universiteit Brussel
Improved management and impermeability of refrigerants is a leading solution to reverse global warming. Therefore, crank-driven reciprocating refrigerator compressors are gradually replaced by more efficient, oil-free and hermetic linear compressors. However, the design and operation of an electromagnetic actuator, fitted on the compression requirements of a reciprocating linear compressor, received limited attention. Current research mainly ...
How can power-to-ammonia be robust? Optimization of an ammonia synthesis plant powered by a wind turbine considering operational uncertainties Vrije Universiteit Brussel
The increasing share of wind energy induces a strain on the electricity network. To unburden the transmission system operators from this strain, the dispensable wind energy can locally be stored in an energy carrier, e.g. ammonia (NH 3). Existing work considers fixed operational parameters during design optimization to represent real-life conditions of the Power-to-NH 3 system. However, uncertainties significantly ...
Experimental investigation on laminar burning velocities of ammonia/hydrogen/air mixtures at elevated temperatures Vrije Universiteit Brussel
The present study introduces new laminar burning velocity data for ammonia/hydrogen/air mixtures measured by means of the outwardly propagating spherical flame method at atmospheric pressure, for previously unseen unburned gas temperatures ranging from 298 to 473 K, hydrogen fractions ranging from 0 vol% to 60 vol% in the fuel and equivalence ratios in the range [0.8–1.4]. Results show increasing velocities with increasing hydrogen fraction ...
A CFD-based methodology for aerodynamic-aeroacoustic shape optimization of airfoils Vrije Universiteit Brussel
The dominant noise mechanism in most rotating machines and aircrafts is trailing edge noise. In particular, wind turbines are seeing ever greater usage, however their noise pollution is a consistent challenge. Current trends in noise reduction mechanisms focus on utilizing additional components, rather than the optimization of the basic airfoil profile a priori. The existing literature regarding a priori shape optimization for noise reduction ...
