Abstract

The current study aims to systematically conduct lab-scale experiments to gain a fundamental understanding of controlling mechanism. This work involves investigations on combustion behavior in presence of coupled external heat sources as well as heat sinks under varying conditions of, linear and non-linear spatial configurations, temporal/ unsteady analysis of energy transfer prediction, for varying surface orientations(s) and arrays configurations. Different configurations of external heat sources and heat sinks were experimented with under diverse conditions and changes in the pilot fuel combustion rates were systematically assessed. The combustion characteristics viz., flame spread rates, flame structure, and thermal decomposition were studied. The requirement for improved fire safety and combustion knowledge to support the testing, validation, and design of future missions in a variety of environments is what motivates this research. To optimize propulsive designs for effective performance and minimization of current shortcomings. The results are likely to help in devising accurate energy prediction systems by developing suitable correlations on the basis of experimental outcomes for efficient energy transfer prediction and thus better and safer missions.
