Worked on enhancing thermodynamic modeling within the RWTH-EBC/AixLib repository by implementing an enthalpy-based state representation for the TwoPhaseSeparator component. This involved refactoring the code to use enthalpy rather than temperature as the primary state variable, updating mass flow source and sink interfaces, and revising internal calculations for density and temperature to ensure consistency with the new approach. Leveraged Modelica for model development and applied skills in fluid dynamics and thermodynamics to improve numerical stability and modeling fidelity. Contributed to code documentation and review, laying groundwork for future cross-component optimizations and maintainable, collaborative development within the library.
