Outline of Final Research Achievements

For multi-scale flow phenomena concerning to fuel cell performance, a hierarchical multi-physics simulation concept is investigated to couple between molecular dynamics, non- equilibrium thermodynamics and unsteady flow simulation. Validations and improvements of mathematical models and numerical methods are performed on the following problems; 1) unsteady coupling simulation of cell / stack level performance of fuel cell design, 2) validations of lattice Boltzmann method for gas-liquid interface simulation and water transport models in catalyst layer, and 3) gas-liquid mixed gas simulation with 6-site potential model for water molecule.
