Description

This command can be used to specify the oxide growth parameters for reaction and diffusion of oxidant. Both dry and wet oxidation can be stored.

Material Specification

This parameter can be used to specify the material the parameters apply to. In general the command should apply to oxide or gas.

dry,wet

The type of oxidation data being specified. One of these two parameters must be specified.

l.break,lin.1.0,lin.h.0,lin.h.3,l.pdep

The linear reaction rate parameters (B/A in the Deal Grove model[32]). This model allows for a dual dependence. L.break specifies the temperature break point. The lin.l parameters specify an Arrhenius relationship below the break temperature and lin.h specify the rate above the break point. l.pdep specifies the dependence on pressure. The rate constant is multiplied by the pressure raised to the l.pdep power.

p.break,parl.0,parh.0,par.h.e.,p.pdep

The parabolic reaction rate parameters (B int eh Deal Grove model [32]). This model allows for a dual dependence. P.break specifies the temperature break point. The par.l parameters specify an Arrhenius relationship below the break temperature and par.h specify the rate above the break point. p.pdep specifies the dependence on pressure. The rate constant is multiplied by the pressure raised to the p.pdep power.

henry

This specifies Henry's gas constant for the oxidant int he gas stream. It is used to compute the gas boundary condition, and is linearly dependent on the pressure.

theta

This represents the number of oxidant particles which must be incorporated to form a unit of oxide.
