Experiments were performed during the first divertor operational phase (OP1. 2a) of the
Wendelstein 7-X stellarator to verify predictions of potential overload conditions …

The Wendelstein 7-X stellarator is in final stages of commissioning, and will begin operation
in late 2015. In the first phase, the machine will operate with a limiter, and will be restricted to …

The function of the high heat flux scraper element is to reduce the heat loads on the element
ends of the actively cooled divertor of Wendelstein 7-X. The scraper element is actively …

The modeling capability for tubes with twisted tape inserts is reviewed with reference to the
application of cooling plasma facing components in magnetic confinement fusion devices …

The Wendelstein 7-X stellarator experiment is scheduled to start operation in mid-2015, and
to move to steady-state operation in 2019. During this steady-state operation, certain plasma …

Twisted tape inserts are commonly used for heat transfer enhancement in fusion
applications. Although these devices have been extensively studied, existing correlations …

Long-pulse operation of the Wendelstein 7-X (W7-X) stellarator experiment is scheduled to
begin in 2020. During this operational phase the vessel will be equipped with water-cooled …

The goal of this work was to perform a computational investigation into the thermalhydraulic
