description Droplet combustion is crucial to the performance of engines and thermal systems, including diesel engines, gas turbines, and rocket engines. Understanding how droplets evaporate, ignite, and burn is crucial for enhancing combustion efficiency, improving fuel utilization, and reducing emissions. However, modeling the coupled heat and mass transfer processes in such systems remains a challenge. This study presents a simplified but physically grounded model for droplet combustion that integrates flame-sheet theory and convective enhancement into a one-dimensional combustor framework. The model assumes quasi-steady behavior, spherical symmetry, and consistent thermophysical properties, allowing for the analytical and numerical prediction of key parameters, such as droplet lifetime, burning rate, and temperature distribution. Simulation results confirm that smaller droplets evaporate completely within the combustor, while larger droplets may result in incomplete combustion. Velocity and temperature profiles align well with physical expectations, and the fuel-air equivalence ratio stabilizes downstream, validating the model’s assumptions. Overall, the model effectively links droplet-scale dynamics with system-level combustion behavior, offering practical insights for optimizing fuel injection, combustor design, and emission performance in a wide range of propulsion and power systems.
