Optimizing the Radial-to-Axial Duct Geometry for a Gas Turbine Radial Compressor Impeller

Optimizing the Radial-to-Axial Duct Geometry for a Gas Turbine Radial Compressor Impeller

By Oleg Dubitsky
Apr 13, 2018

Many gas turbines with radial compressors utilize a radial-to-axial inlet duct upstream of the first compressor stage. Aside from the fact that flow in the duct generates aerodynamic losses, the flow...

Optimizing the Screw Inducer for a Pump

By Oleg Dubitsky
Feb 16, 2018

High-efficiency, low-cavitation pumps often require a screw type inducer to treat the inflow to the main radial/mixed flow pump blades. Efficiency and head rise, split between inducer and main pump,...

Getting to the Root Cause of a Catastrophic Impeller Failure

Getting to the Root Cause of a Catastrophic Impeller Failure

By George C. Zitka, P.E.
Oct 27, 2017

Finding the root cause of a failure by narrowing down multiple overlaid symptoms can be a long and tedious process—and very often the true underlying problem is not what one might expect by a casual...
