The simulaion results reproduce several main properties of IRE. Comparison between the numerical results and experimental observation indicates fairly good agreements regarding nonlinear behavior, such as appearance of localized helical distortion, appearance of characteristic conical shape in the pressure profile during thermal quench, and subsequent appearance of the m=2/n=l type helical distortion of the torus."}, title = {Numerical Simulation of Internal Reconnection Event in Spherical Tokamak}, year = {1999} }
