Abstract

Summary form only given. The growth and saturation of the m=0 magnetohydrodynamic (MHD) instability is numerically studied in a cylindrical Bennett equilibrium in the presence of sheared plasma flows with the aid of a 2D MHD code (MHRDR). Using Fourier analysis the amplitude of different axial modes is followed from the linear to the nonlinear regime. Their linear growth is measured and compared to the results obtained by solving the ideal MHD linearized equations and to the results obtained using a 3D hybrid simulation code
