Abstract

Gelled propellants are a propulsion system fuel whose rheological properties are modified by the addition of a gellant, usually a polymeric or colloidal substance, leading to the liquid fuel having a very viscous liquid, or gel-like consistency. Gelled propellants offer many advantages over conventional liquid propellants such as greater control over the energy density, as well as, ease of transportation and storage (like solid propellants). In this work, we study the combustion dynamics of a single polymer-infused fuel droplet, using both experiments and numerical simulation. The droplet is suspended over a flat flame and different stages of combustion are captured. Using the observations from the experimental data, we formulate a theoretical model for the internal dynamics of the polymer-infused fuel droplet till the end of the initial stage. The resulting partial differential equation is solved numerically and is compared against the experimental data. © 2024 by ASME.
