5.1.1.4.2. gemini_model.corrosion.correlation.dld_model

DLD CO2 corrosion correlation (de Waard, Lotz, Dugstad, 1995).

Implements the semi-empirical correlation described in “Influence of liquid flow velocity on CO2 corrosion: A semi-emperical model” for predicting corrosion rate as a function of CO2 fugacity, temperature, and hydrodynamics. https://www.osti.gov/biblio/106125

Classes

DLD()

class gemini_model.corrosion.correlation.dld_model.DLD

Bases: Model

CO2 corrosion rate using the DLD (1995) correlation.

Initialize DLD corrosion model.

calculate_output(u, x)

Calculate output based on input u and state x.

get_corrosion_rate(u)
