Rheological Characterization of Hydrogen Peroxide Gel Propellant

Abstract: An experimental investigation on the rheological behavior of gelled hydrogen peroxide at different ambient temperature (283.15, 293.15 and 303.15 K) was carried out in this study. The gel propellant was rheologically characterized using a rheometer, in the shear rate ranges of 1 to 20 s -1 , and 1 to 1000 s -1 . Hydrogen peroxide gel was found to be thixotropic in nature. The apparent viscosity value with some yield stress (in-case of shear rate 1 to 20 s -1 ) drastically fell with the shear rate.In the case … Show more

“…The gel fuels are still in a very early stage as many studies are being conducted for their feasibility and redundancy in its application to space exploration. One such type of gel fuel is ethanol based system formulated by introducing gelling agent such as derivative of cellulose [1][2][3][4][5]. Ethanol was selected based on its application in past as a rocket fuel used for German V-2 missile, Jupiter C, American Redstone Rocket, etc.…”

“…The time between fluid contact and ignition is a function of mixing, chemical kinetics, heat transfer, initial temperature, ambient temperature etc. Especially, for a gel propellant system where viscosity and viscoelastic properties play a vital role [1][2][3][4][5], it has to overcome flow resistance for initiating flow and fuel-oxidizer mixing for exothermic chemical reaction [6][7][8][9]. A marked difference in the physio-chemical properties of the gel system in comparison to conventional liquid propellants may lead to significant changes in their ignition and combustion behaviors.…”

“…In this article, the choice of mass fraction of components in a gel fuel was based on these parameters (type of gelling agent and its weight percent). The criterion for choosing the mass fraction of components for gelation of parent fuel is based on the viscoelastic property which in turn depends on type and weight percent of gelling agent [6][7][8][9][10][11]. The references [6][7][8][9][10][11] discuss the detailed understanding of gel fuel formulation and its rheological characterization.…”
