Modified polynomial function model for reversed-field pinches
نویسندگان
چکیده
A generalized analytic representation for the magnetic field and current density profiles in a reversed-field pinch (RFP) is proposed. These profiles have zero current density at the wall and finite plasma pressure. The profiles are characterized by two free parameters here taken to be the field-reversal parameter (F> and pinch parameter (0). From the profiles, many useful quantities such as magnetic energy, beta, inductance, resistance, and Ohmic input power are calculated. These quantities provide a basis for analyzing experimental data and performing electrical circuit modeling of RFP discharges.

A circular equilibrium model for local gyrokinetic simulations of ion temperature gradient fluctuations in reversed field pinches
A simple large-aspect-ratio (R0=r) circular equilibrium model is developed for low-beta reversed field pinch (RFP) geometry. The model is suitable for treating small scale instability and turbulent transport driven by ion temperature gradient (ITG) and related electron drift modes in gyrokinetic simulations. The equilibrium model is an RFP generalization of the common tokamak s-a model to small...
متن کاملEffect of a resistive vacuum vessel on dynamo mode rotation in reversed field pinches
Locked ~i.e., nonrotating! dynamo modes give rise to a serious edge loading problem during the operation of high current reversed field pinches. Rotating dynamo modes generally have a far more benign effect. A simple analytic model is developed in order to investigate the slowing down effect of electromagnetic torques due to eddy currents excited in the vacuum vessel on the rotation of dynamo m...
متن کاملModified Structure Function Model Based on Coherent Structures
In the present study, a modified Structure Function was introduced. In this modified Structure Function model, the coefficient of model was computed dynamically base on the coherent structure in the flow field. The ability of this Modified Structure Function was investigated for complex flow over a square cylinder in free stream and a low aspect ratio cylinder confined in a channel. The Results...
متن کاملSearch for low – dimensional chaos in a reversed field pinch plasma
An analysis of experimental data from the RFX (Reversed Field eXperiment) reversed field pinch machine [L.sion Eng. Des. 25, 315 (1995)] is carried out to investigate the possible existence of deterministic chaos in the edge plasma region. The mathematical tools used include Lyapunov exponents, Kaplan–Yorke dimension, minimum embedding dimension estimates and nonlinear forecasting. The whole an...

Abstract In order to determine the best water production function (CWPF) for predicting grain yield of a soybean crop four models were evaluated. The four functions evaluated were Jensen (1968), Minhas et al (1974) and modified Stewart et al (1977) and modified Bras and Corodova (1981) models. Field experiments were carried out for evaluation of the models. The grain yields simulated by the c...
