.TRANSFORM.Media.ClosureModels.MassDiffusionCoefficient.Models.ArrheniusEquation .TRANSFORM.Media.ClosureModels.MassDiffusionCoefficient.Models.ArrheniusEquationThis model returns the coefficient D_abs using the equation:
D_abs = D_ab0*exp(-Ea/(R*T)^b)
If pre-defined data parameters are to be used then specify the row number of the desired substance(s).
Below is the definition associated with each entry of the dataTable:
