The interfaceOxideRate
is a simple model to calculate the formation rate of oxide inclusions (mDotOxide
), which is a local function of the volume fraction of reducing agent (alpha
), temperature (T
) and oxide-inclusion density (chi
).
The oxide-inclusion formation rate is modelled as follows:
with
where
= | Oxide-inclusion formation rate [kg/(m^3 s)] | |
= | Oxide-inclusion formation rate constant [kg/(m^3 s)] | |
= | Formation factor due to volume fraction of reducing agent [-] | |
= | Formation factor due to temperature [-] | |
= | Formation factor due to oxide-inclusion density [-] | |
= | Volume fraction of reducing agent [-] | |
= | Local temperature [K] | |
= | Solidus temperature of reducing agent [K] | |
= | Liquidus temperature of reducing agent [K] | |
= | Critical oxide-inclusion density [kg/m^3] | |
= | Current oxide-inclusion density [kg/m^3] |
