## What Fluid Model Should I Choose?

by on Apr 30, 2021 11:00:00 AM

When starting a turbomachinery design, the first choice an engineer has to make is the thermodynamic model. The actual fluid type (air, water, R1234ze, etc) is usually clear enough, but what model approach should be selected? Looking at the fluid dialog in Concepts NREC software shows a myriad of options to choose from.

## How Many Pieces of Turbomachinery do You Have in Your House?  (and a Pop Quiz)

by on Apr 16, 2021 11:00:00 AM

On occasion I’m invited to a local middle school to give a talk to one of the science classes about ‘What Is Turbomachinery, and How Does It Work?’.   I teach in several of the turbomachinery design courses we give at Concepts NREC, and while I’m comfortable in those courses, presenting at this level was different. I originally found it a challenge to come up with a good presentation that would keep the students' attention, while still providing some science education as requested by the science teacher that invited me. Derivation of the Euler turbomachinery equation was probably out. The attention getters that seemed to work best to get the conversation going included bringing our turbocharger cut-away (definitely the biggest hit of anything I brought), along with other interesting impeller samples. From there getting into the purpose of various types of turbomachinery (compressor vs turbine vs pump) and a very high level discussion of energy transfer to/from a fluid, seemed to flow. Getting them thinking about some of the physical aspects of turbomachinery operation (Just how fast is 100,000 rpm?) also seemed to keep their attention.

## What’s the Difference Between ‘Preliminary’ And ‘Detailed’ Design, And How Do These Design Phases Fit Into Your Turbomachinery Design Project?

by on Apr 2, 2021 11:00:00 AM

Whether it’s a compressor, turbine, or an entire rocket turbopump design project we are tackling at Concepts NREC, we typically divide the design project into three phases: (1) scoping or feasibility study, (2) preliminary design, and (3) detailed design.   Each of these phases has a specific purpose, although where one phase ends and the next phase begins can vary from project to project.   The purpose and need for a scoping study was described in my blog posted last month, Why are Scoping Studies Necessary for Your Turbomachinery Project? In this blog I will describe the difference between preliminary design and detailed design.

## Ways to Learn Turbomachinery: Textbooks, Professional Development Courses, Custom Courses

by on Mar 5, 2021 11:00:00 AM

Chances are your formal university education didn’t fully prepare you for the real world application of turbomachinery design. The foundation is usually there (fluid mechanics, thermodynamics, structural mechanics, etc.) but applying it effectively on the job usually requires some extra help. On-the-job training is one method, but there are other resources available to help you along. At Concepts NREC we specialize in providing advanced education and technology to the turbomachinery industry. There are several options available for your professional improvement.

## Why are Scoping Studies Necessary for Your Turbomachinery Project?

by 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 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 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 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.
