On the computation of thermo-physical properties of hydrocarbon fuels in a high pressure oxidizing environment.

Abstract

Two methods have been presented for the evaluation of the composition of the different phases of hydrocarbon fuel-oxidizer syctem. The first method, assuming the vapor phase to consist of oxidizer only, gives the composition of the liquid phase. In the second method, a realistic approach that the liquid and vapor phases consist of the oxidizer and fuel both, a representation of the actual situation encountered in the combustion of the fuel droplet, has been adopted. The liquid and vapor phase compositions have been predicted and compared with experimental results for a number of systems. This technique is particularly useful for the systems for which no data other than the temperature and total pressure is available. The method for the evaluation of the interaction co-efficient between the components of the system has also been presented.
