Table 1 Summary of stochastic model variations with effective diffusion coefficient \(D^{*}\), convective fluid velocity v, and drainage coefficient r in (1)

From: Uncertainty quantification of parenchymal tracer distribution using random diffusion and convective velocity fields

Model \(D^{*}\) v r
D1 Random variable 0 0
D2 Random field 0 0
V1 Constant Random influx and outflux field 0
V2 Constant Model V1 + additional velocity field 0
V3 Constant Random influx field \(r > 0\)
