Increasing the Energy Efficiency of Gas Boosters for Hydrogen Storage and for Refueling Stations
A new electrically driven gas booster is described as an alternative to the classical air-driven gas boosters known for their poor energetic efficiency. These boosters are used in small scale Hydrogen storage facilities and in refueling stations for Hydrog ...
MDPI2023Real-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 LTD2020The Role of Reynolds Number Effect and Tip Leakage in Compressor Geometry Scaling at Low Turbulent Reynolds Numbers
Jürg Alexander Schiffmann, Markus Diehl, Christoph Schreiber
In compressor design, a convenient way to save time is to scale an existing geometry to required specifications, rather than developing a new design. The approach works well when scaling compressors of similar size at high Reynolds numbers but becomes more ...
2020Impact of large tip clearance ratios on the performance of a centrifugal compressor
Jürg Alexander Schiffmann, Markus Diehl
Ultra-compact and fast spinning turbomachinery is a key technology to increase performance of domestic heating applications and to address decentralization of power and heat as a consequence of the rise of renewable energy sources. Recently, a heat pump us ...
