Viscous effects in the liquid conductor model of hard-core pinch

  • G. S. Murty


The influence of viscous forces on the instability of liquid conductor model of hard-core pinch is investigated theoretically. It is shown that these forces decrease considerably the growth rate of instability in the experiments of Lehnert and Sjögren. An order of magnitude of the reduction is obtained for the experimental conditions. It is suggested that as a result of viscous forces, the time scale of instability, if any, is so large that instabilities cannot be observed in these experiments when the inner and outer currents are parallel.
