Earlier published engineering notes
KTI has completed the development of a high performance numerical modeling software package named the Computational All-Time Algorithm Package with Underlying Lawrence Technology (CATAPULT) for the numerical simulation of compressible and incompressible multiphase flows.
"All-Time" indicates CATAPULT's capability to model flows in both the compressible and incompressible time scales.
Having both compressible and incompressible flow solver modules provide an efficient method to advance solutions for transient flows that are compressible at early times and incompressible at later times, e.g., rising fireballs resulting from blasts.
The numerical schemes employed by CATAPULT consist of advanced numerical methods developed by the research group at the Lawrence Berkley National Laboratory.
What the PDFs allow us to say
should be pointed out that the researchers recognized the eventual need to provide a method that model s the complete flow fi el d and establ i shes surface pressure detail s, Therefore, they contracted with the Boeing Company in 1973 to develop a higher order panel method to model the Seading-edge vortex flow.
A schemauc of the resulting theoretical model, known as the ""Pre vortex sheet" "VS) method, -is shown on the right of figure 7 and will be described later.
AS so supported was the devel opmenhf soine free vortex f i lament approaches i n the university community to determine if they might provide a simpler method that woul d sati sfy the design and analysis needs.
Further details of this portion of the study are provided in Appendix G.
Effect of Pulsed Blowing on CCW Fluid Dynamics- CFD Results 2.9 Circulation Control has a number of other uses.
It may be used to modify the spanwise lift distribution of wing sections, effectively altering the span loading of lift forces.
Since the trailing vortex structures are directly affected by, and related to the bound circulation, one can modify the strength (or spatial distribution) of trailing vortex structures, including the strong vortex that forms at the wing tips.
Attempts were made to study the benefits of 3-D Circulation Control.
The first is a streamwise tangential blowing on a wing-flap configuration.
The second is a spanwise tangential blowing over a wing with a rounded wing tip.
-dimensional cases, the above concept is also applicable by treat- ing each chordwise vortex integral in a similar manner as in eq.
In this case, not only chordwise control and vortex locations are defined by the semi- circle method, but also the sparrwise vortex strips and control locations.
