Abstract

A simulation of discharges in Damavand tokamak is presented using a 0-D model. Time evolution of some parameters of tokamak plasma can be calculated by the 0-D model. The 0-D model is applied to the Damavand tokamak with five differential equations. These equations consist of the density conservation equations of the electron and neutral particles, the power balance equation, and the primary and secondary circuit of the ohmic heating transformer (OHT). From the 0-D model, the time evolution of plasma current, the primary current of the OHT, the time evolution of the electron temperature and electron density, and the neutral particle density can be obtained. The results of the simulation were compared with some of the experimental results obtained in the Damavand tokamak.
