Abstract Reduced-gravity experiments were performed to investigate combustion characteristics of individual monopropellant droplets composed of hydroxylammonium nitrate (HAN), methanol, and water. The experiments were conducted using the 2.2 Second Drop Tower at the NASA John Glenn Research Center at Lewis Field in Cleveland, OH. Gravitational levels were about 10 −4 times normal gravity and experiments were performed in air at about 25 °C and with pressures from 0.1 to 1 MPa. Droplets initially...

Abstract Experiments on combustion of heptane/hexadecane mixture droplets were conducted in a reduced-gravity environment. Initial droplet diameters ranged from 0.47 to 1.5 mm, and initial hexadecane mass fractions ranged from 0.05 to 0.4. The ambient gas was O2/He (with O2 mole fractions of 0.3 and 0.5), or atmospheric air, and pressures were varied from 0.033 to 0.3 MPa (abs). A previous asymptotic theory was extended to allow data on flame contractions to be used to estimate liquid species di...
