Introducing SpinOffs - The Blog

by Barbara Shea on Sep 23, 2016 10:59:18 AM

Today, Concepts NREC is launching our new online blog, named SpinOffs as an homage to the company's printed newsletter of the same name.  The company’s first newsletter came out in 1986 with the goal of sharing exciting innovations, unique applications, case studies, product development and opinions focused on engineering issues.  For the next thirty years a printed newsletter filled with in-depth technical content was sent out to subscribers from around the globe. The name changed over the years, from NREC News, to Spin, and finally to SpinOffs, but the original goal remained the same. SpinOffs, the blog, will also keep the goal of the original newsletter intact and provide the ability to leave comments and ask questions. We look forward to sharing what’s new, next and notable in the turbomachinery industry with you. Thank you for reading!

The Future of Turbomachinery Software

by Mark R. Anderson on Sep 9, 2016 11:27:00 AM

The turbomachinery and software industries have evolved, in tandem, to high levels of maturity. On the engineering side, improved modeling capability and access to more powerful computational resources have revolutionized the design process, reducing costs and significantly improving performance and reliability. On the manufacturing side, additive manufacturing is starting to open up exciting new possibilities by allowing component shapes that simply were not possible before.  Like all technology, the evolution of these methods may seem clear enough for the near future, but it can be much more hazy over the long-term. Therefore, this article will take a look at what the future of  turbomachinery software may hold.  
Expanding design capabilities for advanced high-performance turbines for steam and organic Rankine cycle power generation is a constant area of focus in developing Concepts NREC’s Agile Engineering Design System ® (AEDS) software. Cycle and operation requirements, as well as a wide range of operating conditions and volumetric flows, are often required for the design of turbines with diverse geometries. Some typical design tasks and available new/existing features within AEDS are described here.

Benefits of the Cooled Turbine Airfoil Agile Design System

by Concepts NREC on Sep 1, 2016 1:30:00 PM

Achieving optimum performance and efficiency in a gas turbine engine requires pushing operating temperatures as high as possible. In fact, many gas turbine engines in service today operate at hot-gas temperatures which are much greater than the incipient melting point of typical turbine airfoil base alloys. Successful operation in this extreme gas temperature environment requires turbine airfoils be designed using special high-temperature alloys, metallic and ceramic coatings, and complex cooling configurations.

The CN300: Converting Low Temperature Heat to Electric Power

by Concepts NREC on Sep 1, 2016 1:23:00 PM

Concepts NREC introduces licensing for its new compact, high-speed, hermetically sealed turbogenerator. Nominally rated for 300 kWe, the CN300 is designed for converting low temperature heat to electric power using an Organic Rankine Cycle (ORC) process.   Historical Perspective Increasing concerns for protecting the environment and the escalating cost of energy itself have raised interest in energy conservation to an all-time high. This interest extends to waste heat recovery systems. These systems produce electric power by converting thermal energy to electrical energy. And, when site conditions involve temperatures too low for conventional heat recovery systems, ORC processes become the best solution. These are typically defined as any heat source at temperatures below 800oF. In fact, according to one U.S. Department of Energy report, there could be as much as 1.5 to 2.0 quadrillion BTU/year of heat with temperatures below 500oF available from exhaust gas streams in the industrial sector alone. Naturally occurring heat sources may be just as plentiful.

Extremely High Suction Performance Pump Inducers

by Concepts NREC on Sep 1, 2016 9:30:00 AM

The path to better operation stability and robustness High suction performance pump inducers are critical to important industrial and advanced aerospace applications where the required inlet pressure is near the vapor pressure of the liquid to be pumped. These include boiler feed pumps, liquefied natural gas (LNG) transfer pumps, aircraft fuel pumps and space vehicle propellant pumps. Improving the efficiency of moving natural gas from production sites to where it is used is an increasingly important application for high suction performance inducers. Over the past 17+ years, Concepts NREC has been researching ways of improving inducer design to advance inducer suction performance, operational range, stability, and structural robustness.
