Abstract:

The objective of this Phase I research is to implement a conservative method for transferring data across arbitrary nonoverlapping zonal interfaces in the CFD code GASP version 3.0. This task will involve a linear interpolation of primitive variables in three dimensions with a gradient weighted flux correction method aimed at maintaining global flux conservation. For applications such as complex internal flows and hypersonic vehicles where engine/airframe integration analysis is crucial, sophisticated multi-block structured grid techniques are required. These techniques must not only be flexible and easy to use, but they must also be accurate. An arbitrary zonal interface interpolation scheme with global flux conservation will provide these characteristics. The Phase II portion of this research will build on the Phase I work by considering additional state variable interpolations, nonoveralpping grid topologies, time accurate calculations with moving grids, and interpolation across zonal boundaries between a structured and unstructured mesh. At the conclusion of this work, we will deliver and demonstrate the code to the Air Force including installation, software listings, a new GASP manual, and a training class.
