The Local Limit of Global Gyrokinetic Simulations
- 1. University of Maryland, College park, Maryland (United States)
Description
OAK-B135 Global gyrokinetic simulations of turbulence include physical effects that are not retained in local flux-tube simulations. nevertheless, in the limit of sufficiently small ρ* (gyroradius compared to system size) it is expected that a local simulation should agree with a global one (at the local simulation radius) since all effects that are dropped in the local simulations are expected to vanish as ρ* → 0. In this note, global simulations of a well-established test case are indeed shown to recover the flux-tube limit at each radius
