N2 - © 2019 by the author(s); In this paper we consider the effects of vortex diffusion in two paradigmatic inhomogeneous physical situations; radial heat flow between two concentric cylinders, and vortex decay in a finite cylindrical container. Diffusion effects may strongly modify the expected results for the vortex length density L as a function of the heat flux q, leading also to dynamical unexpected features, relating L to time in decay, or to hysteresis behaviour of L for increasing/decreasing heat flux.
