Survey of Processors for Space
نویسنده
چکیده
Processors for space are required to be tolerant to the following radiation and environmental effects: TID (100300 kRad for GEO and beyond, 10-50 kRad for some LEO missions), Latch-up, SEU, SET, SEFI, and temperature cycles. Another reliability issue is the complete and permanent failure of a processor or a critical sub-component. None of the methods surveyed here mitigate such failures, and the common mitigation method is based on deploying spare computers in combination with either a central reconfiguration circuit or a distributed recovery mechanism.

Mixed Large-Eddy Simulation Model for Turbulent Flows across Tube Bundles Using Parallel Coupled Multiblock NS Solver
In this study, turbulent flow around a tube bundle in non-orthogonal grid is simulated using the Large Eddy Simulation (LES) technique and parallelization of fully coupled Navier – Stokes (NS) equations. To model the small eddies, the Smagorinsky and a mixed model was used. This model represents the effect of dissipation and the grid-scale and subgrid-scale interactions. The fully coupled NS eq...
