This study examines the thermal behavior of a laser ignited thermite composed aluminum and bismuth trioxide. Temperature data were collected during reaction using four-color pyrometer high-speed color camera modified for thermography. The two diagnostics arranged to collect simultaneously, with similar fields view acquisition rates, so that techniques could be directly compared. Results show at...

Formulations of aluminum nano particles for energy applications have been intensely investigated over the past few decades for their attractive energy release rate. They significantly affect propellant burn rates, enhance detonation properties, and are also used in thermite formulations (“Super-Thermites”) [1]; however, the reactive properties remain poorly understood. The mechanism behind thes...

This article provides a computational analysis of the reaction fully-dense layered aluminum and copper oxide systems. After detailed presentation 2D nonstationary model implementing both oxygen diffusion, propagation front in an Al/CuO thin film was studied. The qualitatively reproduces dependency progression rate spatially as function fuel concentration. Calculations also evidence inverse evol...

3D-printing methods are used to generate reactive material architectures. Several geometric parameters are observed to influence the resultant flame propagation velocity, indicating that the architecture can be utilized to control reactivity. Two different architectures, channels and hurdles, are generated, and thin films of thermite are deposited onto the surface. The architecture offers an ad...
