Behavior of a Parafoil - Fluid/Structure Interaction Problem
Johnny Wu
This project involves a fluid-structure interaction problem analyzing
the behavior of a parafoil subjected to turbulent flow using the
finite element method.
The software used to simulate this problem was developed by the T*AFSM.
In this project, Mr. Wu was helped by Dr. Vinay Kalro, at that time a
research associate supervised by Tezduyar.
Part I: Rigid Parafoil- Flow Simulation Problem
The first part of the project involved a fluid interaction problem analyzing
the coefficients of lift and drag of the parafoil at different
angles of attack. Three differently shaped parafoils were used.
The first mesh was a open inlet mesh. The second mesh was a closed
inlet mesh. And the third mesh was a rounded closed inlet mesh. Various
refinements were also used to test the coefficients of lift and drag.
Triangular elements were used in these unstructured meshes. Theses
meshes were created with 2DModelG. The code
was run on a multiprocessor SGI Onyx.
Part II: Deformable Parafoil - Fluid-Structure Interaction Problem
The next step was to see how a deformable parafoil anchored
to one point would look like under a turbulent flow. The numerical
methodology is based on advanced finite element formulations and implementation
of these formulations on parallel supercomputers.
