Finite element modelling of transport in a tokamak edge and divertor

Richard Marchand2002年Plasma Physics and Controlled FusionIF 2.2出版社

A finite element approach is described, for modelling transport in tokamak edge and divertor plasma. The method discretizes all transport equations on an unstructured triangular mesh. The advantages and difficulties of this approach are discussed. Results are presented and compared with experimental measurements made on TdeV. Example results are also given for JET, using a simplified physics model (single ion species, no neutrals and no flux limits), and using a more comprehensive model with helium impurity ions and neutrals.

トカマク周辺部およびダイバータにおける輸送をモデル化するための有限要素法アプローチについて述べる。本手法は、すべての輸送方程式を非構造三角形メッシュ上で離散化する。このアプローチの利点と困難について議論する。結果は、TdeVで行われた実験測定値と比較して提示される。また、JETに対する結果例も示す。これには、簡略化された物理モデル(単一イオン種、中性粒子なし、フラックス制限なし)を用いた場合と、ヘリウム不純物イオンおよび中性粒子を含むより包括的なモデルを用いた場合の両方が含まれる。
