Descripción de la oferta de trabajo:
The Department of Chemical and Biochemical Engineering, Center for Energy Resources Engineering (CERE), invites applicants for a PhD position on the capabilities and limitations of the classical primitive electrolyte equation of state approach.
This PhD project is part of the ERC Advanced Grant 'New Paradigm in Electrolyte Thermodynamics' (ElectroThermo) and in particular of the work package (WP2) which is about exploring the limits of the primitive electrolyte equation of state (e-EoS) approach using both in-house e-EoS and those developed by external colleagues. There is an established collaboration with IFP Energies Nouvelles, France and NCSR Demokritos, Greece with whom a 'protocol' database for testing the e-EoS should be developed. Two postdocs in the WP2 investigating the external models will work mostly at IFP Energies Nouvelles and NCSR Demokritos.
Responsibilities and tasks
The overall target of this PhD project is the further development and validation of the electrolyte Cubic Plus Association (e-CPA) EoS, which is based on the primitive approach, previously developed at CERE, DTU Chemical Engineering in the PhD theses of Dr. Bjørn Maribo-Mogensen and Dr. Anders Schlaikjer and published in a series of articles.
First of all, in collaboration with the external partners, a 'protocol database' (for development but especially for validation) should be developed. The database should include a wide range of properties (phase behavior, densities, thermal, hydration energies), systems and conditions (T, P, molality, etc.) in order to ensure a comprehensive test of the models. It is of paramount importance to assess the 'true' applicability of the primitive approach using the different development methodologies selected by the various partners.
For the e-CPA development to be carried at DTU, besides the comparisons to the other approaches, the following aspects will be considered:
- Evaluation of the input from molecular simulations and single-ion activity coefficients either at the development or at the validation phases;
- The 'concentration limits' and approximations of the Debye-Hückel (DH) equation will be evaluated by comparing the full explicit form, simplified forms and numerical solutions of the Poisson-Boltzmann equation;
- The limits of the DH model for asymmetric electrolytes and the need for corrections like those proposed by Onsager;
- The relative significance of the Born term and whether improved representations of the 'hydration' terms are needed within the primitive methodology;
- The role of the dielectric constant will be analysed;
As mentioned, the overall target of the project is to evaluate the capabilities and limits of the classical primitive e-EoS approach where physical (incl. association) effects are enhanced by electrostatic effects, via DH or Mean Spherical Approximation (MSA) theories, and possibly also the Born term. How far can we go with these and when do we need additional contributions from ion-pairs or other effects (ion-ion, ion-solvent associations). Implementation of additional terms is not within the scope of this project but the various needs for further developments should be discussed.
Candidates should have a two-year master's degree (120 ECTS points) or a similar degree with an academic level equivalent to a two-year master's degree.
A strong background on thermodynamics, mathematical modelling, and programming experience is essential.
