Abstract

In order to do consistent scrape-off-layer plasma and neutral transport calculations, the 2D fluid code B2 has been externally coupled to the neutral transport code DEGAS for DIII-D. The coupling procedure is similar to simulations done for TFTR (Tokamak Fusion Test Reactor), Tore Supra, and CIT (Compact Ignition Tokamak). An 'average' source approach is utilized to allow convergence between the two codes. Initial comparison of plasma quantities between the coupled code set and the B2 code alone shows that a colder, denser plasma may exist at the divertor targets than predicted by the B2 code with its internal recycling model.
