摘要
The effects of compressibility on the Rayleigh-Taylor instability in Z-pinch implosion plasmas are investigated by means of simple slab geometry.The linear mode equation,which includes main steady-state quantities and their gradients,is derived.Numerical solutions are presented.The incompressible fluid result is also obtained.These results indicate that the linear growth rate of the Rayleigh-Taylor instability for the compressible magnetohydrodynamic fluid is far larger than one in the incompressible situation.Therefore,the compressible systems are all more unstable than the incompressible ones.
The effects of compressibility on the Rayleigh-Taylor instability in Z-pinch implosion plasmas are investigated by means of simple slab geometry. The linear mode equation, which includes main steady-state quantities and their gradients, is derived. Numerical solutions are presented, The incompressible fluid result is also obtained. These results indicate that the linear growth rate of the Rayleigh-Taylor instability for the compressible rnagnetohydrodynamic fluid is far larger than one in the incompressible situation. Therefore, the compressible systems are all more unstable than the incompressible ones.
