We utilize large scale computations to examine the intricate details of the flow structure, design experiments and test physical models. Our group has access to multiple million cpu-hour allocations via resource allocations at NSF-supported TeraGrid resources such as Ranger at TACC (UT Austin) and Kraken at NICS (U. Tenn./ORNL) as well as other DoE and DoD supported machines, which are among the most powerful supercomputers currently available to academic researchers in the world. In addition, we perform simulations on an in-house maintained 32-node cluster, larger department clusters, and TAMU supercomputers. A suite of in-house and commercial simulation and visualization software are used to chariacterize flow structure, verify mathematical model performance, and aid in experimental design.
