摘要

Progress in RFP dynamics and transport studies is described. The compressible, three-dimensional code SPECTR3 has been modified to include toroidal effects, and classical resistivity and thermal conductivity. These transport effects are treated implicitly. A three-dimensional, incompressible MHD code is being developed. It will be computationally more efficient than the existing code, and will be used extensively if compressibility is determined to be unimportant. Post-processor codes to analyze data generated by the nonlinear code have been developed. Three-dimensional computer runs at low beta (= B/sub theta/(a)/) have found the development of a substantial stochastic core, with good flux surfaces being retained in the outer part of the discharge. Runs at high beta are underway. We are collaborating with the ETA-BETA-II experimental group at Padua, Italy, in an attempt to interpret measured internal fluctuations and profiles in terms of resistive MHD. The emphasis of this work is on the effect of MHD fluctuations plasma transport. Analytic studies of the RFP dynamo have begun. We are attempting to find steady state solutions with flow to the resistive MHD equations. A set of reduced equations has been developed, and preliminary numerical experiments are being performed.
