A generalized multi-dimensional mathematical model for charging and discharging processes in a supercapacitor
TL;DR: In this article, a generalized three dimensional computational model based on unified formulation of electrode-electrolyte system of an electric double layer supercapacitor has been developed, which is analogous to porous media theory employed for electrochemical systems.

Kevin T. Clarno,Bobby Philip,William K. Cochran,Rahul S. Sampath,Srikanth Allu,Pallab Barai,Srdjan Simunovic,Mark Berrill,Larry J. Ott,Sreekanth Pannala,Gary A. Dilts,Bogdan Mihaila,Gokhan Yesilyurt,Jung Ho Lee,James E Banfield +14 more
TL;DR: The AMP Nuclear Fuel Performance code as discussed by the authors leverages existing validated material models from traditional fuel performance codes and the Scale/ORIGEN-S spent-fuel characterization code to provide an initial capability that is shown to be sufficiently accurate for a single benchmark problem.

A parallel multi-domain solution methodology applied to nonlinear thermal transport problems in nuclear fuel pins
Bobby Philip,Mark Berrill,Srikanth Allu,Steven P. Hamilton,Rahul S. Sampath,Kevin T. Clarno,Gary A. Dilts +6 more
TL;DR: An efficient and nonlinearly consistent parallel solution methodology for solving coupled nonlinear thermal transport problems that occur in nuclear reactor applications over hundreds of individual 3D physical subdomains by leveraging knowledge of the physical domains, the physics on individual domains, and the couplings between them within a Jacobian Free Newton Krylov method.
