PUMPAL®

CAE Software for Axial and Radial Pumps

A meanline approach is used to design centrifugal pumps and mixed-flow pumps with single and multiple stages. PUMPAL® is used to design the stage, analyze performance, refine the parameters with data reduction, and model the machine according to several performance models. PUMPAL's unique Design Wizard leads the user through all the necessary steps for design, analysis, and data reduction. The meanline pump design can easily be sent to the AxCent®program for further blade design and fluid dynamic analysis.

Components Supported by PUMPAL:

  • Inlet guide vanes
  • Open or closed impellers
  • 2D or 3D impellers
  • Front and rear seals (multiple)
  • Diffuser types, including…
    • Arbitrary vaned
    • Vaneless
    • Wedge/channel
    • Cascade
    • Conical
    • 90/180 degree bends
  • Exit elements, including…
    • Collector
    • Volute
    • Return channel
  • Various leakage paths
  • Multistage pumps

Modeling

PUMPAL supports two-elements-in-series (TEIS) rotor diffusion modeling, two-zone loss modeling, radial and axial stator diffusion/losses, volutes, inlet cavitation, disk friction, exit mixing, cavity leakage, and more. PUMPAL uses the same consistent model of the stage performance for design, analysis, and data reduction modes.

Integrated Performance Map Plotting

Review design performance, analysis, and test data with flexibly plotted performance maps, updated automatically with each geometric change.

Easy Editing

View the pump stage in an active, true-scale meridional view. Edit the parameters by double clicking on the component in the meridional view. Parameters can also be edited using a single text input/output file, a feature especially useful for optimization.

Tabular View of Results

View the results in a flexible, spreadsheet-like table format, customizable through separate filters. Create any number of filters, select what to display, and customize the labels as well.

Axial View with Inlet and Exit Velocity Triangles

Using the window view, view blades and velocity triangles at the impeller inlet and exit. View inlet velocity triangles for the hub, tip, or RMS radius, and exit velocity triangles for the primary and secondary zones, and mixed-out state.

A Real Fluid Program

PUMPAL calculates Real Fluid properties using a variety of equations of state options.

Direct Integration with AxCent®

Start AxCent automatically from PUMPAL, with the initial meanline geometry transferred automatically to AxCent. Changes in AxCent that affect the meanline analysis will cause the meanline analysis to be rerun and all performance maps to be regenerated.

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.”

CFD-based Throughflow Analysis: Bridging the Gap Between 1D and 3D Analyses
by Steve Kohr, Director of Software Product Management & UX
Many of us have come to appreciate the expedience that 1D (meanline) analysis provides when scoping out a new design or revisiting a legacy design for use in a new application. However, we also know that this approach to design is heavily reliant on empirical models. Inherent in this design approach is, or should be, the acceptance that these empirical models are highly useful but obviously limiting and maybe not necessarily universally applicable. We are accepting the tradeoff of fidelity for time.

The Gyroscopic Effect
by Thomas Gresham, Senior Mechanical Design Engineer
This post covers one of the fundamental issues that makes rotordynamics a unique subject: The Gyroscopic Effect. The gyroscopic effect can be observed in the behavior of spinning tops, fidget spinners, inertial navigation systems, and many types of turbomachinery. If you have ever tried to tilt an object while it is spinning, then you may have noticed this effect.

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.
