| Abstract: | The rheological characteristics of gelled propellants are introduced briefly. The flow behaviors are classified as three stages and the constitutive equations applied to different shear rates are described. The status of atomization research of gelled propellants with the doublet impinging jet injector, triplet air-blast atomizer, coaxial-swirl injector, pulsatile injector is summarized. Various factors which affect the atomization modes and some problems existing in present atomization research are pointed out. |
