CO2 Lumped Parameter Model Physics Knowledge

This skill provides physics knowledge for the 0-D CO2 lumped-parameter model implemented in the co2lpm package.

When This Skill Applies

• Modifying code that implements concentration evolution equations
• Changing ODE solver logic or state variable handling
• Implementing or modifying emissions partitioning (field, plant, degassing)
• Debugging unexpected simulation behavior
• Planning changes to physics-related code
• Explaining why the model behaves a certain way
• Working with pressure reversal scenarios
