propagation of magnetoacoustic shock waves in cylindrical geometry

cylindrical korteweg-de vries-burgers (ckdvb) equation for magnetoacoustic wave is derived for dissipative magneto plasmas. two fluid collisionless electromagnetic model is considered and reductive perturbation method is employed to study the propagation ofmagnetoacoustic shock waves in cylindrical geometry. two level finite difference method is employed by using runge-kutta method to solve ckdvb equation numerically. the effects of nonplanar geometry, plasma density, magnetic field strength, temperature dependence and kinematic viscosity on magnetoacoustic shocks are investigated. the numerical results are also presented for illustration.
