FUEL 104 |
| The objective of this research project is to develop critical reactor technology by reducing (or increasing the efficiency of) the heat, cost, volume, and weight requirements leading to a hydrogen fuel system that will meet the DOE system-based storage capacity targets. A modeling tool was developed for a hydrogen generation reactor. After constructing a reactor packing sub-module, microscopic modeling of reactant flow in the reactor was performed which then established a macroscopic reactor model. The model was then validated by comparing the results with experimental data for parameters such as: sodium borohydride conversion, axial temperature, overall pressure drop, and hydrogen flow rate. Then other unobservable parameters were simulated, they included: borate concentration, vapor flow, hydrogen distribution, and void fraction. Then a conceptual design was developed based on the parameter optimization of: fuel space velocity, total volume, diameter-to-length ratio, geometry, pressure, heat removal, fuel concentration, and catalyst packing density. |
