Control/CFD
Interdisciplinary Research
Interface Technology
The objective of this research is to develop an integrated
analysis/design system which simplifies the use of CFD codes by
non-CFD experts and which provides a mechanism for applying
control design and validation tools to CFD results. As a means
of meeting these objectives, a graphical user interface is
being developed at NASA Glenn in conjunction with the
University of Akron. It is based on software developed at NASA
Glenn as part of the Integrated CFD and Experiments (ICE)
project and has been demonstrated with the 1-D LAPIN code.
The interface provides a powerful graphical tool for
interactively controlling and monitoring CFD code(s) in real
time. It also provides extensive database management
capabilities for cataloging and archiving results. On-going
research will focus on adapting the interface to the NPARC code
and on integrating standard control analysis tools.

The accompanying figure shows a snap shot of a typical ICE
operating panel. This frame was captured while monitoring the
response of a LAPIN-based inlet simulation to a constant
frequency perturbation. The upper left interface panel is used
to monitor and modify simulation control parameters. The lower
left interface panel provides a mechanism for modifying
boundary conditions that affect the simulation. The upper right
panel (continually updated) shows the time histories of
selected variables. The lower right panel shows the axial
pressure distribution at the current simulation time.
