This webinar is particularly suited for engineers interested in using computational fluid dynamics (CFD) for solving store separation and stage separation problems. Additional general computed motions will be discussed as well.

The use of a six-degree-of-freedom (6 DOF) model will be demonstrated in the context of store and stage separation problems, which involve flow-dependent motions. Comparison to experimental data will be shown as evidence that CFD can be relied upon to replace a majority of the traditional (and expensive) physical testing. One of the store separation examples will feature liquid sloshing inside the store.

More general examples will show how prescribed motions and constrained motions can be specified, and the resulting mesh motion will be highlighted. These general examples will include a check valve, an unfolding fin, and the rotations of the two nacelles of a full model of the V-22 Osprey tiltrotor.

About the presenter:

Christoph Hiemcke, PhD

Dr. Hiemcke has been working at Fluent since 2001. He supported aerospace clients working on airplanes, jet engines, rockets, moving shocks and gun blasts, helicopters, and environmental control systems in spacecraft. His areas of expertise include dynamic mesh problems, as well as transonic and supersonic flows. He was also involved in a number of consulting projects that involved blast waves and traveling shocks. Prior to joining Fluent, Dr. Hiemcke was a professor in the Electromechanical Engineering Department at Loras College in Dubuque, Iowa. He obtained his PhD in Aerospace Engineering from Iowa State University in 1994. His master’s thesis focused on boundary layer theory, while his dissertation dealt with experimental and computational aspects of wings flying close to the ground.
