November/December 2025

Many turbomachinery diagrams are outdated and recommend axial machines over centrifugals, but modern technological advancements must be considered for industrial applications.

Among other causal factors, stress concentrations accumulate in areas with sharp edges, so filleting and chamfering is required to enable the smooth flow of stress streamlines.

The 2025 Turbomachinery & Pump Symposia covered hydrogen compressor testing, new gas seal technology, various pumps for ammonia and supercritical operations, and more.

The precision and efficiency of laser-based welding systems can address key industry challenges, such as labor shortages, operational downtime, and quality consistency.

Mechanical design decisions—ranging from stress management to natural frequency tuning—play a critical role in the reliability of steam turbines across demanding mechanical drive applications.

The November/December 2025 issue covers steam turbine blade dynamics and aerodynamics, gas turbine bucket repair, a TPS 2025 recap, a Q&A with Ebara Elliott Energy, and much more.
