Given global warming, which limits the use of classical energy sources, renewables can
provide a solution to the dilemma between environmental protection and sustainable …

A centrifugal compressor for large-scale supercritical carbon dioxide applications (∼ 50
MW) is analyzed by means of RANS simulations. The purposely designed compressor …

Radial (inflow) turbines with volutes have received limited attention in the body of literature
for open-field wind harvesting. Few existing data in the literature indicate low maximum C p …

The impact of size and working fluid on the efficiency, operating range, and axial thrust on
bearings is examined for high-speed, oil-free centrifugal compressors. First, the …

Large scale, high pressure ratio (PR) centrifugal compressors are commonly made up of a
radial impeller with a vaned diffuser. In research to date, the majority of research and design …

Centrifugal compressor machinery is subject to a potentially damaging phenomenon called
surge at low mass flow rates. This effect may be preceded by a phenomena known as inlet …

Working fluid selection for closed-cycle turbo-refrigerators (CCTRs) for deep freezing, as a
more fundamental topic, has not yet received careful consideration, leading to limitations in …

The advanced design of a centrifugal compressor with high efficiency and wide operating
range is a challenging task due to the complex flow field arising from the three-dimensional …

Radial turbocompressor-driven heat pumps are currently being fostered for their application
in a wide range of novel energy systems. This encourages the development of small …

In today's era of heightened environmental awareness, industries and means of transport
are under increasing pressure to minimize their ecological footprint. In particular, small-scale …
