Abstract
This paper describes a numerical investigation of a surface exposed to a plasma flow for different plasma and material boundary conditions to allow an assessment of laser diagnostic measurements in the boundary layer. The eventual goal is to develop a test case to validate physical and chemical models underlying current gas-surface interaction simulations. Using an existing numerical model, boundary layer gradients of temperature and key species are predicted for different boundary layer edge and surface conditions in an inductively coupled plasma facility. These predictions are then used to assess which species can be measured quantitatively with sufficient accuracy for model validation purposes.
