# Visco-resistive plasmoid instability

@article{Comisso2016ViscoresistivePI, title={Visco-resistive plasmoid instability}, author={Luca Comisso and Daniela Grasso}, journal={Physics of Plasmas}, year={2016}, volume={23}, pages={032111} }

The plasmoid instability in visco-resistive current sheets is analyzed in both the linear and nonlinear regimes. The linear growth rate and the wavenumber are found to scale as S1/4(1+Pm)−5/8 and S3/8(1+Pm)−3/16 with respect to the Lundquist number S and the magnetic Prandtl number Pm. Furthermore, the linear layer width is shown to scale as S−1/8(1+Pm)1/16. The growth of the plasmoids slows down from an exponential growth to an algebraic growth when they enter into the nonlinear regime. In…
