A Comparison of Results from an Edge-Plasma Model with Those from a Two-Dimensional Fluid Code

Abstract

We have just completed a comparison of predictions for the scrape-off layer (SOL) plasma, from a physics model with the more accurate ones from a two-dimensional fluid code, the B2 code. The results presented here show rather good agreement on values of plasma temperature in the SOL and of divertor heat load, for a rather wide range of Tokamak sizes and parameters. We are therefore confident that this model will provide a suitable divertor module for both the new ITER systems code, SUPERCODE, and other applications requiring fast but accurate modelling of edge plasma parameters at least within the range of the present benchmarks.
