Research goals are to develop component processes, test methods for thermophysical properties, and physical mathematical modeling for 1) performance-based fire protection engineering related to wood-based materials used in WUI, 2) economical gasification of biomass and synthesis of syngas into biofuels, and 3) fundamentals of wood pyrolysis and combustion essential to wood thermal degradation and fire growth. This work is being used for predicting fire development on exterior building surfaces and ornamental vegetations for WUI fire scenarios. Thermophysical properties derived from modified test apparatuses are provided for NIST?s Wildland Fire Dynamics Simulator as well as for analytical fire growth models, which are provided as a basis for animated-like 3-D fire growth in real time using desktop computers that has Architectural CAD in conjunction with Google Earth. Fundamental knowledge of wood degradation along with prior private-sector research on process analysis of jet turbine engines are being applied to develop new and economical process for small-scale biomass gasification and conversion of syngas to biofuels. A special bench scale apparatus was built using the liquid metal as heat and mass carriers for directly producing syngas statically from wood, with primarily CO and H2 emissions measured. A continuous biomass flow apparatus has been planned and will be built at unique university facility to investigate conversion efficiency. Other projects included the process modeling of conventional biomass gasification and Fischer-Tropsch synthesis as a biorefinery attached to wood and paper mills in the support of the excellent generic business case of the concept. Various research collaborations nationally and internationally are being developed to promote the above research areas.
