FANPAL
Meanline design optimization for axial, centrifugal and mixed-flow fans
FANPAL allows you to perform meanline analysis for axial, centrifugal or mixed-flow fans. In FANPAL, you can design the stage, analyze the performance, and reduce laboratory data in order to refine your input parameters. You have a maximum degree of flexibility in modeling the performance of your machine, according to a variety of different, but qualified, performance modeling approaches.
FANPAL allows you to easily migrate your fan design into the AxCent® application for further blade design and fluid dynamic analysis.
FANPAL supports:
- Radial or axial inlet guide vanes
- Open or closed impellers
- 2D or 3D impellers
- Front and rear seals (multiple)
- Diffusers (up to 20)
- generic
- vaneless
- wedge/channel
- cascade
- conical
- 90 degree bends
- 180 degree bends
- foil
- Exit elements
- collector
- volute
- combustor
- return channel
- Various leakage paths
- Multistage fans
Design Wizard Technology
FANPAL’s unique Design Wizards lead the user step-by-step through
the design, analysis, or data reduction process.
Modeling
FANPAL supports Two-Elements-in-Series (TEIS) rotor diffusion modeling,
two-zone loss modeling, single-zone rotor loss modeling, disk friction,
exit mixing, radial and axial stator diffusion/losses, volutes,
stall, thrust, and other fundamental fluid dynamic aspects of fan
performance
True-Scaled Meridional View of Stage
The fan stage is shown in a true-scaled view.
Integrated Performance Map Plotting
Powerful and flexible plotting of performance maps allows quick
review of performance and comparison of multiple designs or analyses
versus test data. Maps are updated automatically with any geometry
change.
Easy Editing
Parameter entry is accomplished by double-clicking on the appropriate
component in the meridional picture.
Tabular View of Results
Results may be viewed in a flexible, spreadsheet-like tabular view.
Tables are customizable through separate “filters.” Users can create
any number of filters, selecting what to display as well as customizing
the labels.
Axial View with Velocity Triangles
Blade angles and velocity triangles may be viewed at both the impeller
inlet and exit.
OLE Automation Support
Control of FANPAL can be accomplished from an external program through
industry-standard Object Linking and Embedding (OLE) automation.
Full control of data entry, program execution, and result retrieval
is supported through OLE automation. External programs can be written
in Visual Basic, C++, FORTRAN, or any other language which supports
Microsoft’s OLE standard.
Multistage Capability
Multistage analysis and data reduction are supported. A variety
of multistage performance maps are available within FANPAL.
Preliminary Mechanical Analysis
FANPAL provides the user with an initial calculation of mechanical
properties of the design. Stress, vibration, and fatigue limit estimates
are rapidly provided and access a wide database of customizable
material properties.
FANPAL is a Real Fluid Program
Real Fluid properties can be calculated in FANPAL using the optional
DB Robinson Real Fluid property routines. Users can also incorporate
their own proprietary fluid properties.
Direct Integration with AxCent
The user can start AxCent automatically from within FANPAL,
with initial 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.
The figure below shows the 3D geometry sent to AxCent from FANPAL.
