The study of aerodynamic performance in compressor blades is critical for optimising the efficiency and reliability of modern turbomachinery. Recent work has focused on the dual challenges of ...

EPRI (Electric Power Research Institute) reports that 7FA gas turbines have a rotor life of about 144,000 hours, or 5,000 starts. The primary life-limiting factor is high cycle fatigue cracks ...

Mechanical Dynamics & Analysis (MD&A) completed compressor blade replacement work on two 7FA units, including full inspections, and ongoing operational recommendations. We were responsive to emerging ...

A fan prototype will be installed as part of a vapour compressor at the refrigeration plant at AngloGold Ashanti's Mponeng mine. Refrigeration plants are generally required in deep-level mining where ...
