Gelled propellants behave as non-Newtonian fluids and are promising for future aerospace application because they combine the advantages of solid propellants with those of liquid propellants. Spray formation of gel simulants from swirl injectors was described by carrying out experiments in a spray test facility. A high speed camera was used to record detailed information about the liquid sheet breakup...
A novel technique of flyash utilization was presented and mullite ceramics were prepared from flyash and desilication-flyash. The effect of desilication process was analyzed and the result shows that the only difference between flyash and desilication-flyash lies in the silica content, which is caused by the removal of silicate glassy phase during the desilication process. The physical and mechanical...
