Time scales of dynamic stall development on a vertical-axis wind turbine blade
Karen Ann J Mulleners, Sébastien Le Fouest, Daniel Marie Fernex
Vertical-axis wind turbines are excellent candidates to diversify wind energy technology, but their aerodynamic complexity limits industrial deployment. To improve the efficiency and lifespan of vertical-axis wind turbines, we desire data-driven models and ...
2023An Integrated Approach to Designing Robust Turbocompressors on Gas Bearings Through Surrogate Modeling and Constrained Multi-Objective Optimization
Jürg Alexander Schiffmann, Soheyl Massoudi, Cyril Picard
Designing turbocompressors is a complex and challenging task, as it involves balancing conflicting objectives such as efficiency, stability, and robustness against manufacturing deviations. This paper proposes an integrated design methodology for turbocomp ...
2023Information-Driven Gas Distribution Mapping for Autonomous Mobile Robots
Alcherio Martinoli, Chiara Ercolani, Faezeh Rahbar
The ability to sense airborne pollutants with mobile robots provides a valuable asset for domains such as industrial safety and environmental monitoring. Oftentimes, this involves detecting how certain gases are spread out in the environment, commonly refe ...
MDPI2023The dynamic stall dilemma for vertical-axis wind turbines
Karen Ann J Mulleners, Sébastien Le Fouest
Vertical-axis wind turbines (VAWT) are excellent candidates to complement traditional wind turbines and increase the total wind energy capacity. Development of VAWT has been hampered by their low efficiency and structural unreliability, which are related t ...
PERGAMON-ELSEVIER SCIENCE LTD2022A novel control strategy with an anode variable geometry ejector for a SOFC-GT hybrid system
A novel control strategy was developed with an anode variable geometry ejector for a solid oxide fuel cell-gas turbine (SOFC-GT) system. The anode inlet temperature was controlled by combining two modes to achieve a greater controllable range: anode variab ...
PERGAMON-ELSEVIER SCIENCE LTD2022Real-time optimization of load sharing for gas compressors in the presence of uncertainty
Dominique Bonvin, Timm Faulwasser, Alejandro Gabriel Marchetti, Predrag Milosavljevic
This paper investigates the problem of load-sharing optimization of gas compressors in the presence of uncertainty. The objective is to operate a set of compressor units in an energy-efficient way, while at the same time meeting a varying load demand. The ...
ELSEVIER SCI LTD2020Theoretical and Experimental Investigation of a Small-scale, High-speed, and Oil-free Radial Anode Off-gas Recirculation Fan for Solid Oxide Fuel Cell Systems
Jan Van Herle, Jürg Alexander Schiffmann, Patrick Hubert Wagner
The Laboratory for Applied Mechanical Design (LAMD) designed, manufactured, and experimentally tested a novel recirculation fan for a 10 kWe solid oxide fuel cell (SOFC). The fan uses oil-free bearings, more specifically herringbone-grooved journal and spi ...
2020Theoretical and Experimental Investigation of a 34 Watt Radial-Inflow Steam Turbine with Partial-Admission
Jan Van Herle, Jürg Alexander Schiffmann, Patrick Hubert Wagner
A micro steam turbine with a tip diameter of 15 mm was designed and experimentally characterized. At the nominal mass flow rate and total-to-total pressure ratio of 2.3 kg/h and 2, respectively, the turbine yields a power of 34 W and a total-to-static isen ...
2020Theoretical and Experimental Investigation of a 34 Watt Radial-Inflow Steam Turbine with Partial-Admission
Jan Van Herle, Jürg Alexander Schiffmann, Patrick Hubert Wagner
A micro steam turbine with a tip diameter of 15mm was designed and experimentally characterized. At the nominal mass flow rate and total-to-total pressure ratio of 2.3 kgh-1 and 2, respectively, the turbine yields a power of 34W and a total-to-static isent ...
2020Variable speed operation of centrifugal pumps running as turbines. Experimental investigation
François Avellan, João Nuno Gomes Borga Delgado
Pumps running as turbines are pointed out as a cost-effective solution for energy recovery in pressurised water supply systems. However, these hydraulic machines feature low efficiency under variable discharge operation due to the lack of an inlet flow contr ...
