5.1.1.4.3. gemini_model.corrosion.correlation.dlm_model

DLM CO2 corrosion correlation (de Waard, Lotz, Milliams, 1991).

Implements the “”predictive model for CO2 corrosion engineering in wet natural gas pipelines””, parameterized by CO2 fugacity and temperature with an empirical scaling factor. https://doi.org/10.5006/1.3585212
