摘要
A non-linear numerical simulation of the dynamo effect of a reversed field pinch (RFP) with finite beta is presented. It is shown that the m=-1, n=(9, 10, 11, …, 19) modes cause the dynamo effect and sustain the field reversed configuration. The role of the m=0 modes on the dynamo effect is carefully examined. Our simulation shows that the magnetic field fluctuation level scales as S-0 2 or S-0 3 in the range of 103<S<105, while Nebel, Caramana and Schnack obtained the fluctuation level is in-dependent of S for a pressureless RFP plasma. © 1990, THE PHYSICAL SOCIETY OF JAPAN.
