2020 Software Release Feature Highlight: Streamlining the Optimization Process in TurboOPT II™

by Steve Kohr, Associate Director, CAE Product Management on Nov 20, 2020 2:55:55 PM

Concepts NREC’s TurboOPT IITM product was created to provide designers a link between Concepts NREC meanline and 3D design products and 3rd party optimization products. The use of optimization in the design process allows designers to push the boundaries of performance by completing analysis on hundreds, or even thousands, of designs within a given set of design parameters.

 

2020 Software Release Feature Highlight: Importing FINE™/Open Grids and Starting CFD From a Previous CFD Run in pbPost™

by Steve Kohr, Associate Director, CAE Product Management on Oct 30, 2020 3:43:36 PM

Concepts NREC’s pbPost™ product was created to provide designers a turbomachinery-specific pre- and post-processing tool to link our flagship 3D design product, AxCent®, and our partner NUMECA International’s FINE™ CFD products.

 

2020 Software Release Feature Highlight: Axial Design in AxCent®

by Steve Kohr, Associate Director, CAE Product Management on Oct 16, 2020 11:00:00 AM

AxCent® has long been recognized as the premier 3D design software for turbomachinery components.

What’s So Hard About Designing A Pump?

by Daniel V. Hinch, Corporate VP Sales and Marketing, Concepts NREC on Oct 6, 2020 11:00:00 AM

Here at Concepts NREC, we work on a wide range of turbomachinery components designed for fluids ranging from gases to liquids, including supercritical fluids like supercritical CO2 which have properties of both gases and liquids.   We do a lot of pump design, consulting work and education. In fact our annual course on Centrifugal and Axial Pump Design is consistently one of the most popular.   Many engineers in the gas compressor industries consider pump design plain vanilla, without the added complexities of Mach number effects, but there are reasons why our pump course is so popular – pump design can indeed be very difficult, with a number of complicating factors that are unique or especially critical to the pump industry.

2020 Software Release Feature Highlight: Aungier Model Calibration in COMPAL®

by Steve Kohr, Associate Director, CAE Product Management on Oct 2, 2020 11:00:00 AM

In 2019, the Aungier model was added to COMPAL®, our compressor meanline design and analysis product. The Aungier model is a globally accepted, physics-based loss approach to aid in the design of compressors.

Design Considerations for Turbo Expander Supersonic Turbines with Liquid to Gas-Liquid Flow Transition

by Oleg Dubitsky, Corporate Fellow, Director of Corporate Technology on Sep 28, 2020 10:50:05 AM

A small turbine (for ORC, air liquification processes) , operating with low volumetric flows at inlet and significant pressure ratio in a single stage configuration (to reduce costs) is often associated with flow of media with transition from liquid to gas-liquid state, with operating levels of Mach numbers above 1.8 at nozzle exit, that assumes convergent-divergent nozzle geometry, and may require partial admission.

Using an Economizer in Centrifugal Compressor Chiller Cycles

by Daniel V. Hinch, Corporate VP Sales and Marketing, Concepts NREC on Sep 18, 2020 11:00:00 AM

In the chiller industry, the evolution of centrifugal compressor chiller cycles has led to an interesting and powerful cycle and related compressor configuration which involves reinjection of refrigerant between stages. Such systems are thermodynamically identified broadly as cascade cycle options and have the common objective of improving the Coefficient of Performance (COP) of the standard refrigeration cycle.

Optimization using Dakota in Concepts NREC’s TurboOPT II

by Rachel Moore, Senior Software Engineer on Sep 11, 2020 11:00:00 AM

Automated optimization is becoming more and more common place in the turbomachinery industry today.  What was once exclusively the domain of academics and high-end researchers, has become much more widespread today.  The rise of optimization is directly related to ever increasing computer power available and the advent of new software tools to set it up.  Virtually every category of turbomachinery has adopted it, at least to some degree.  One can find many examples of advanced optimization in the open literature but more practical applications can add value to your product line in a very reasonable time and effort.  

Super Critical CO2 Compressor Design

by Mark R. Anderson, CTO of Concepts NREC on Aug 14, 2020 11:00:00 AM

Super critical carbon dioxide power (sCO2) cycles are attracting a lot of interest these days all over the world. Many initiatives using various levels of private and public funding are in progress in several countries right now. Preliminary testing on small scale units have shown that such systems are technically viable. The next round of larger scale testing under way now will determine if the concepts are financially viable as well.

Turbomachinery Design for Medical Devices Including Compressors, Fans, Blowers, and Pumps

by Daniel V. Hinch, Corporate VP Sales and Marketing, Concepts NREC on Aug 7, 2020 11:00:00 AM

Turbomachinery is used in a very wide variety of industries and applications.   While applications like aerospace ‘jet engines’ or powerplant steam turbines are the applications that come to mind for a lot of people, turbomachinery is integrated with or buried in a huge range of other equipment, and often transparent to the user.   I give a talk to local middle school sciences classes on what turbomachinery is, and give a quiz at the end of the talk where I ask them to list every piece of turbomachinery in their home. The students have surprised me with their understanding and reasoning ability, and I now have a list of 20 to 30 examples of turbomachinery running in their homes.
