Mass transport due to a concentration gradient • the electrical conductivity σ [(Ωm)−1] for transport of electrical charge, • the diﬀusivity D [m2/s] for transport of mass. Forahomogeneous material, C canonlydepend onpositionthroughanydependence of ϕ. For isotropic materials, C must have a form which is independent of all spatial directions; hence all sets of orthogonal axes . Yasuaki Ichikawa A.P.S.
