Estimating the non-dimensional energy of vortex rings by modelling their roll-up

The non-dimensional energy of starting vortex rings typically converges to values around 0.33 when they are created by a piston-cylinder or a bluff body translating at a constant speed. To explore the limits of the universality of this value and to analyse ...

Emission reduction by targeted transient operations in three-way catalysts for heavy-duty natural gas applications

Moyu Wang

To curb the severe effects of climate change, our society needs to radically reduce its CO2 footprint. For the heavy-duty sector, where electrification is difficult, alternative fuels can be the solution. Methane-fueled engines have lower energy-specific C ...

Contribution to the Technique of Compressed Air Energy Storage

Mahbod Heidari

Development of intermittent solar and wind energies and the demand peak increase has made energy storage very important in energy policy. Thus, energy storage will play a key role in enabling the world to develop a low-carbon electricity system. An interes ...

Preliminary techno-economic, environmental and risk assessments of a hybrid solarised gas turbine concept

In the power generation sector, substituting fossil-fuels with near-zero carbon alternatives is one viable option identified for curbing CO2 emissions. Solar energy is one such alternative and it's valued for being inexhaustible in nature. This study exami ...

Isothermal transcritical CO2 cycles with TES (thermal energy storage) for electricity storage

Daniel Favrat, Young Min Kim

Recently, TEES (thermo-electric energy storage) systems have been proposed as a new method for large-scale energy storage wherein electric power is stored as thermal energy by using a heat pump and retrieved from the TES (thermal energy storage) by using a ...

Electromagnetic Environment Associated with Lightning Strikes to Tall Strike Objects

Seyed Abbas Mosaddeghi

The study of the lightning interaction with tall strike objects has attracted considerable attention of lightning researchers lately. Many lightning measurements including current and associated electromagnetic fields were recently made all over the globe ...

Stirling-Wärmetransformator für die Beheizung von kleinen und mittleren Wohnbauten.

Daniel Favrat

Several years ago it has been demonstrated experimentally and verified theoretically that Vuilleumier heat pump systems (a combination of a Stirling engine with a Stirling heat pump) can be supercharged periodically by means of an attached resonance tube, ...
