The development and characterization of aluminum fueled power systems and a liquid aluminum fuel
Various aluminum-water reactions were thermodynamically analyzed across a wide range of temperatures and pressures to determine the most favorable reaction under each condition. Results show that under most achievable temperatures and pressures the reaction will produce AlOOH, however at low …

Sensitivity Analysis of Turbulent Free-Surface Flows Applied to Optimal Casting Rigging Design
… mold were studied using water as an analog of liquid aluminum. Further, laminar filling experiments using solutions of glycerol and water were performed. As such, errors in the flow prediction could be attributed to either the VOF algorithm or the turbulent mixing length model. The results show …

Pathways to a Family of Low-Cost, High-Performance, Metal Matrix Composites Based on Aluminum Diboride in Aluminum
… based on the in-situ formation of AlB2 flakes in liquid aluminum is described. First, a new synthesis technique for the preparation of high aspect ratio AlB2 is demonstrated. Borax and B2O 3 were reacted with molten aluminum to prepare high aspect ratio AlB 2. The focus then shifts to further …

Radiative heat transfer from aluminum oxide in solid propellant flames
… in aluminized propellant flames was determined. Liquid aluminum oxide (Al$\sb2$O$\sb3$) particles, produced from the distributed combustion of aluminum droplets, dominated the optical characteristics of aluminized propellant flames. A laser scattering and extinction technique was developed to …
