Gelled fuels have arisen as a potential replacement for conventional solid and liquid propellants since they combine the attractive properties of liquid and solid materials.The time dependence on the rheological properties of gelled fuels can play an important role in the design of injection, atomization and combustion systems. The present paper presents the Non-Newtonian and thixotropic behavior of silica/hydrocarbon fuel gels. Viscosity measurements showed qualitatively evidence of thixotropicity in the fluid. In addition, no recovery was observed when the sample was left to rest for long times.
