Part two of this myth on centrifugal compressor maps delves into the map’s extrema: surge and choke.

Part one of this two-part myth on a centrifugal compressor map covers the basic physics of the constant speed head-flow performance lines.

Supercritical CO2 (sCO2) may not have superpowers, but turbomachinery operators try to avoid working near the critical point at all costs.

Turbomachinery coatings are designed to be an added layer of protection for base materials, but even coatings wear down.

CFD is a great tool, but it takes experienced engineers to get accurate results.

Green hydrogen is receiving a lot of hype in the news, but a closer look reveals how impractical its future is for power generation.

Part one of this two-part myth on reciprocating versus centrifugal compressors addresses design and application differences.

Open and shrouded impellers both offer advantages, which are reflected in the respective applications they are used for.

Reciprocating and centrifugal compressors are viable options for hydrogen compression with enhanced and adapted sealing methods, alternative valve selections, and additional staging.

Dual drivers—a combination of an electric motor and a gas turbine to power a centrifugal compressor—play on the individual strengths of each driver in a single package.

What are cross-coupling forces really, and should I judge my rotor system stability on them?

Debunking the Myth: Embracing Gearboxes for Enhanced Efficiency in Compressor Applications

The current trend in manufacturing is toward single-piece manufacturing. However, in many cases, there is no justifiable reason or logic behind this.
