Understanding turbulence and mix in compressible flows is of fundamental importance to real-world applications such as chemical combustion and supernova evolution. The ability to run in three dimensions and at very high resolution is required for the simulation to accurately represent the interaction of the various length scales, and consequently, the(More)

The mission of the Fusion Simulation Project (FSP) is to develop a predictive capability for integrated modeling of magnetically confined burning plasmas. The FSP provides an opportunity for the United States to leverage its investment in ITER and to further the U.S. national interests in the development of fusion as a secure and environmentally attractive(More)
The equilibrium of an infinitely long, strongly magnetized, non-neutral plasma confined in a Penning-Malmberg trap with an additional mirror coil has been solved analytically ͓J. Fajans, Phys. Plasmas 10, 1209 ͑2003͔͒ and shown to exhibit unusual features. Particles not only reflect near the mirror in the low field region, but also may be weakly trapped in(More)
A three-dimensional hydrodynamics code based on the Piecewise Parabolic Method (P PM) is used to examine compressible uid turbulence in three dimensions. The code runs on a number of parallel architectures, including MPPs and SMP clusters. We consider problems of current interest, such as Rayleigh-Taylor and Richtmyer-Meshkov instability and turbulent(More)
