The Tokamak à Configuration Variable (TCV) has recently been equipped with gas baffles to increase its divertor closure for a broad range of magnetic geometries. First experimental results reported in Reimerdes et al. (2021) demonstrated compatibility geometries and confirmed the main design constraints baffles, particular an increased neutral pressure. present article presents more in-depths a...

Windage power loss (WPL) is significant and cannot be neglected in a study on transmission efficiency reducing the energy consumption of high-speed gear. The influence mechanism baffle reduction WPL needs to further studied. Based computational fluid dynamics (CFD) technology, this paper puts stress analyzing axial radial baffles viscous pressure effects with groove structures WPL. numerical ca...
