Gyrokinetic flux-driven simulations in mixed TEM/ITG regime using a delta-f PIC scheme with evolving background
Moahan Murugappan, Laurent Villard, Stephan Brunner +3
In the context of global gyrokinetic simulations of turbulence using a Particle-In-Cell framework, verifying the delta-f assumption with a fixed background distribution becomes cha…

System size scaling of triangularity effects on global temperature gradient-driven gyrokinetic simulations
Giovanni Di Giannatale, Alberto Bottino, Stephan Brunner +2
In this work, we explore the triangularity effects on turbulent transport employing global gyrokinetic simulations performed with the ORB5 code. Numerous experiments on the Tokamak…

Ion temperature gradient mode mitigation by energetic particles, mediated by forced-driven zonal flows
Juvert Njeck Sama, Alessandro Biancalani, Alberto Bottino +14
In this work, we use the global electromagnetic and electrostatic gyro kinetic approaches to investigate the effects of zonal flows forced-driven by Alfvén modes due to their excit…
