Abstract
We discuss the interplay between theory, molecular simulation and electric
conductance experiments as an important tool for the extraction of ion-pair
interaction potentials to make possible the bridging of the density gap between the
lowest experimentally attainable conductance measurement and the theoretically
reachable zero-density limit of the ion-pair association constant. Then, we predict
the density dependence of the Na+!Cl! pair association constant in ultra
supercritical steam environments by constraint molecular dynamics simulation
over state conditions relevant to the new generation of ultra-supercritical steam
power plants. Finally, we draw attention to relevant modeling challenges
associated to the behavior of these systems around the zero-density limit and
discuss ways to overcome them.
