Wall boundary conditions for rough walls
Progress in Computational Fluid Dynamics, An International Journal, 2007The treatment of rough walls is still a considerable challenge in computational fluid dynamics. Empirical wall functions are available to bridge the flow and shear stress in the near-wall computational cells to the wall distance and roughness. The concept of equivalent sand-grain roughness has been applied.

Abstract ORMAK is a diffuse toroidal pinch with typical plasma currents of 100 kA, electron temperatures of 800 eV, and ion temperatures of 300 eV. The walls of the plasma region are made of stainless steel coated with an intermediate layer of platinum 0.5 μm thick and an outer 1–2 μm layer of gold.

Abstract This article presents plans for wall conditioning for ITER. Typical machine parameters are 1.5 GW of fusion power and 1000 s of DT burn duration. To achieve these plasma, the wall conditioning is required in ITER. For baseline methods, glow discharge cleaning for zero-magnetic field, and electron cyclotron resonance discharge cleaning and ...

Abstract Like all tokamaks, ITER will require wall conditioning systems and strategies for successful operation from the point of view of plasma-facing surface preparation. Unlike today’s devices however, ITER will have to manage large quantities of tritium fuel, imposing on wall conditioning a major responsibility for tritium inventory control.

Abstract We summarize the experience gained over two years on the wall conditioning of TEXTOR by radiofrequency assisted DC glow discharges (RG-discharges). The importance of the contamination history of the wall for the cleaning rate in H2 RG-discharges is underlined. RG-discharges in hydrogen already lead to some sputter erosion of the wall.
