Oral session 9 - Stellarator dynamics and transfport: O9
- Chair: Alessandro Zocco
A relatively simple way to evaluate bootstrap current in stellarators involves the use of the long mean free path asymptotic formula by Shaing and Callen [1]. This formula contains all the information about device geometry in a geometrical factor, independent of plasma parameters. This method is particularly suited for stellarator optimization, where multiple quick estimates of bootstrap...
Recent advances in stellarator optimization have led to unprecedented improvement in neoclassical transport in Wendelstein 7-X [1] such that anomalous transport is contributing a significant portion of the transport, especially in the Scrape-Off-Layer (SOL) [2]. Here, we present isothermal fluid turbulence simulations using the BOUT++ framework [3,4] in the edge and scrape-off-layer (SOL) of...
