2D streamer simulations using the high order fluid model

In 1D, the recently derived high order fluid model [Dujko et al, J. Phys. D, 46:5202, 2013] shows promising performance and accuracy compared to the classical first order model using the local field approximation [Markosyan et al, J. Phys. D, 46:5203, 2013]. Here we simulate cylindrically symmetric streamers between two planar electrodes with the high order fluid model. The system is discretized using finite volume spatial discretization (high-resolution scheme) and explicit time stepping. We discuss the results and compare with previous work.
