Burning Rate Studies on the Closed Chamber Combustion of a Fuel Air Propellant.
Abstract
Closed chamber studies were performed on the combustion of the fuel air propellant JP4 and air. Densities of loading were varied from 0.18 to 0.36 gm/cubic centimeters. Equivalence ratios were varied from 0.6 to 2.7 fuel to air. A method for calculating the effective burning rate is presented. It was found that a wide variation in the actual burning rate can be obtained depending, approximately, on the inverse of the fuel air mixing time and, to a lesser extent, on the equivalence ratio. The pressure-time data is used to interpret the pressure rise predicted by an isothermal model, an adiabatic model, a reduced pressure model, and a volumetric model. Comparison of the results demonstrated that the reduced pressure model and the volumetric model offer the best pressure-time correlation. (Author Modified Abstract)
