High Performance Computing for Stability Problems - Applications to Hydrodynamic Stability and Neutron Transport Criticality

Subramanian, Chandramowli

Abstract:
In this work we examine two kinds of applications in terms of stability and perform numerical evaluations and benchmarks on parallel platforms. We consider the applicability
of pseudospectra in the field of hydrodynamic stability to obtain more information than a
traditional linear stability analysis can provide. Furthermore, we treat the neutron transport criticality problem and highlight the Davidson method as an attractive alternative to the so far widely used power method in that context.
