Sandpile model with tokamaklike enhanced confinement phenomenology.
نویسندگان
چکیده
Confinement phenomenology characteristic of magnetically confined plasmas emerges naturally from a simple sandpile algorithm when the parameter controlling redistribution scale length is varied. Close analogs are found for enhanced confinement, edge pedestals, and edge localized modes (ELMs), and for the qualitative correlations between them. These results suggest that tokamak observations of avalanching transport are deeply linked to the existence of enhanced confinement and ELMs.

متن کاملSelf-organized criticality in sandpile models
The sandpile model, introduced in 1987, was the first model to exhibit self-organized critical behavior, that is, the system moved towards its critical point without the need to tune any adjustable external parameter. In this paper, we look at the why these models exhibit such non-intuitive behavior. We also look at some of the phenomenology near the critical point, such as scaling laws and cri...
متن کاملSandpile dynamics as a paradigm for turbulent transport
In order to shed some light on the apparent discrepancies between most theoretical models of turbulent transport and experimental observations of the transport in magneticly confined plasmas, a model for transport1 has been developed based on the concept of self-organized criticality (SOC)2. This model seeks to describe the dynamics of the transport without relying on the underlying local fluct...
متن کاملSelf Organization of Edge and Internal Pedestals in a Sandpile
The temperature profiles of magnetically confined plasmas can display distinctive longlived pedestals at the edge and internally. Here we show that such structures can arise naturally through avalanching transport in a sandpile model. A single control parameter that is constant across the sandpile determines the occurrence and regularity of these effects, as well as the entrainment of global co...
متن کاملAn SOC-like avalanche distribution observed in an MHD turbulent cascade in the solar wind
We calculate for the first time the probability density functions (PDFs) P of burst energy e, duration T and inter-burst interval τ for a known turbulent system in nature. Bursts in the earth-sun component of the Poynting flux at 1 AU in the solar wind were measured using the MFI and SWE experiments on the NASA WIND spacecraft. We find P (e) and P (T ) to be power laws, consistent with self-org...
