Software Highlights

AXIAL's state-of-the-art loss modeling system allows for the independent selection of loss models by blade row and loss split by loss component (i.e., profile, secondary flow, partial admission, wetness losses, and more). Industry-standard loss models are included for turbines.

  • Ainley-Mathieson
  • Dunham-Came
  • Kacker-Okapuu
  • Moustapha-Kacker

Loss models are included for compressors.

  • Koch & Smith
  • Wright & Miller

Real Fluid thermodynamics are integral to AXIAL, which includes built-in support for perfect and semiperfect fluid properties. Real Fluid properties are provided through several different fluid databases including DB Robinson Real Fluid Properties, NIST, and ASME Steam. AXIAL also supports condensed gases, user-modifiable fluid properties, and the barotropic fluid thermodynamic model.

AXIAL includes a flexible user-friendly interface and built-in performance mapping. Context-sensitive help is included for each parameter in each table cell. HTML help is also available.

AXIAL utilizes integrated performance map plotting. Users can view blade angles and velocity triangles at the rotor inlet and exit, as well as view results in a flexible spreadsheet-like table view. Tables are customizable through separate filters, with the user able to create any number of filters, select what to display, and customize the labels as well.

Users can control AXIAL from an external program by means of Object Linking and Embedding (OLE) automation. OLE automation supports the full control of data entry, program execution, and result retrieval. External programs can be written in Visual Basic, C++, FORTRAN, or any other language that supports the Microsoft® OLE standard.

AxCent files can be started from within AXIAL, with the initial geometry and flow parameters transferred automatically to AxCent for blade shaping/stacking, blade-to-blade analysis, throughflow analysis, and further transfer to CFD and FEA programs. The user can also update the AXIAL solution from AxCent, transferring the more complete geometry from AxCent back to the meanline model.

Other AXIAL Features

  • Estimate of hub and tip flow parameters
  • Evaluation of compressor stall and choking conditions for both compressors and turbines
  • Design analysis of multiple choked and stalled components, along with mass flow, pressure ratio, and power
  • Setup of an arbitrary sequence of stage elements (rotor, stator, duct, IGV, EGV, etc.)

I came to the realization that we needed some objective insight.

We were working well with the OEM but even with our combined efforts, we were struggling to get a critical compressor to pass performance on their test stand. Although I'd never directly done business with Concepts NREC I was familiar with them and their capability so I chose to contact them when I came to the realization that we needed some objective insight. Concepts NREC fielded my cold call and immediately engaged their expertise in a complex problem that was also challenged by schedule constraints. They provided increased understanding of an already complex CFD which resulted in increased confidence that the proposed solution would succeed on the next test stand attempt (which it did!). We are pleased to have had the help of Concepts NREC and now have a well-performing compressor in our process.”

Part 2: Hydrogen Turbomachinery Design
by Mark R. Anderson, Chief Technical Officer, Concepts NREC
Hydrogen is attracting a lot of interest in different circles these days from: propulsion, to energy storage, to personal transportation. The most obvious benefit of hydrogen fuel is a total lack of carbon in the exhaust products. This is rare for a fuel that’s a fairly high energy substance to begin with. More specifically, its high energy in terms of energy per unit of weight but somewhat less so in terms of volume.

Part 1: Hydrogen and Turbomachinery
by Dr. David Schowalter, Sr. Director, Global Software Sales
Because of its promise as a non-polluting fuel, hydrogen is currently a very popular topic among the energy and turbomachinery communities. If hydrogen is reacted with pure oxygen, the thermal energy release is significant, and water is the only by-product. This highly exothermic reaction was used to get humanity to the moon. Of course, nitrous oxides (NOx) can be released if hydrogen is burned in air. If, on the other hand, the energy from the reaction is converted to heat and electricity in a fuel cell, then only water vapor is discharged. In addition, when pressurized in a tank, hydrogen is an easily transportable fuel, and so is desirable for transportation.
