Extending the Operating Range of Centrifugal Compressors

by Adam Weaver on Sep 28, 2018 10:36:51 AM

Extending the operating range of centrifugal compressors has been a highly sought-after goal for several decades. In fact, the potential benefits have motivated researchers to develop and put into practice many pieces of technology, including full span inlet guide vanes (IGV’s), complex multistage systems with interstage bleed, passive casing treatment, and many others.

Designing Turbomachinery is like Solving a Rubik's Cube

by Barbara Shea on Sep 21, 2018 10:01:00 AM

I think we can all agree that designing turbomachinery is hard. There are just so many moving parts (pun intended) in the design process, and they are all interconnected.  When you change the blade shape, it changes the aerodynamics, and could impact manufacturability. Everything you change has a cascading effect across many different areas, because all of the areas are linked; just like a Rubik's® cube! Only, in turbomachinery design, you are not always trying to get all of the sides to be one color. Heck, even a 3-year old can do that

Investing in Designing Gas Turbines for Power Generation

by David Teal on Sep 14, 2018 11:46:08 AM

Gas turbines (or GTs) are important in the power generation sector due to their high efficiency, cleaner emissions and faster startup than old coal-powered plants. These power generators can range from small, local power supplies to huge units, large enough to power a city.  Even with the surge in renewable energy sources, there will always be a need for power when the sun goes down, on a windless day or when power peaks are expected. GTs fill this power gap. GTs are very power dense, meaning they can produce a lot of power in a relatively small footprint. This is very useful in a city, offshore, or where vast landmasses are unavailable. 

Trends in Composite Materials for Turbomachinery Applications

by Arsalan Adil on Sep 7, 2018 8:54:51 AM

The advancement of composite material technologies over the past few decades has contributed to their widespread use in a vast array of aerospace applications. Most applications target weight reduction without compromising the strength and endurance capabilities of the metallic structures being replaced. The high-strength composite materials used in advanced applications involving elevated temperature conditions are, typically, continuous fibrous material embedded in a matrix material that acts to hold the fibers together. The fibers in the matrix material can be oriented in various directions to achieve the desired mechanical properties in any specific direction. Weight reduction is achieved by eliminating redundant fiber material for the directions in which material strength and stiffness are not required by the design.
