Swelling Interface Number

The swelling interface number is important in describing the relationship between solvent penetration and solute diffusion.

The swelling interface number equals the penetration speed times the swollen-phase thickness divided by the diffusion coefficient.

Formula

QuantityVariable["Sw", "SwellingInterfaceNumber"] == (QuantityVariable["v", "Speed"]*QuantityVariable["δ"["t"], "Thickness"])/QuantityVariable["D", "DiffusionCoefficient"]

symbol description physical quantity
Sw swelling interface number "SwellingInterfaceNumber"
D diffusion coefficient "DiffusionCoefficient"
v penetration speed "Speed"
StringJoin["δ"["t"]] swollen-phase thickness "Thickness"
