Description
A 13CH4 injection experiment with a test limiter in TEXTOR is modeled by EDDY and ERO for the purpose of
code-code benchmarking. The 2D patterns of CH emission of both codes agree with the experiment. The 13C
deposition patterns on the limiter surface are reproduced assuming negligible effective sticking (S=0) for returning
hydrocarbons. The 13C deposition efficiency decreases with increasing injection time, and it reaches a steady state
value accompanied by a depth profile of 13C. The measured 13C deposition efficiency (~0.1%) is reproduced,
assuming negligible sticking of returning hydrocarbons and high re-erosion yield of redeposited carbons (of the order
of 10 times larger than graphite). The sticking probability and re-erosion yield are still unknown parameters, which
determine erosion and deposition of plasma facing materials.
