Why are Scoping Studies Necessary for Your Turbomachinery Project?

by Daniel V. Hinch, Corporate VP Sales and Marketing, Concepts NREC on Feb 19, 2021 11:00:00 AM

At Concepts NREC we do a lot of projects from ‘clean sheet’ all the way through manufacturing of prototype hardware.   In fact, these types of projects are among the favorite of the engineering staff – create what never was, and quickly get to see it produced in hardware and often tested. For these types of projects, we strongly suggest that we complete a ‘scoping study’ as the first phase of the project.

Accelerating a Career in Turbomachinery CAM and Manufacturing Solutions During a Pandemic

by Kate Guerrina, Marketing Manager on Dec 4, 2020 1:49:55 PM

The global health crisis has presented business and industry with uncertainties we could not have anticipated. Here at Concepts NREC, we've worked hard to adapt for the health and safety of our colleagues and for our business. That means, among other things, that I and the majority of my colleagues have been physically separated since early March. I miss them. I miss seeing their faces and those brief hallway conversations-in-passing that later prove to be invaluable learning moments. 

So now, more than ever, I wonder what kind of person accelerates their career mid-pandemic and moves directly into a virtual office with fewer opportunities for learning tribal knowledge. Our CAM solutions group recently hired a Product Manager into that situation, so I asked what made him comfortable managing our CAM products for turbomachinery. Meet Jonathan Bicknell.

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.
