Abstract
A time-dependent closure for the parallel viscous force is calculated in a bumpy cylinder magnetic field geometry using a Chapman-Enskog-like approach. The calculation is valid for all times and field modulations, and is expressed as a dynamic evolution in time. Two important applications are presented: modification of the frequency-dependent electrical conductivity due to the interaction between trapped and circulating particles, and the parallel flow evolution which can be extended to axisymmetric geometries.
