Abstract
A detailed numerical simulation of n-heptane droplets was carried out on a stationary three-dimensional configuration with complex geometry. The investigations focused on spray evaporation and dispersion within a carrier phase that featured operating conditions similar to those found in industrial applications, i.e. elevated pressure and temperature. The simulations were carried out using the Eulerian–Lagrangian approach with two-way coupling. There were two cases. The first dealt with spray characteristics within the preheated carrier phase without considering combustion. The second investigated the influence of combustion on droplet characteristics. Both cases had the same boundary conditions. The numerical simulations used two models to compute the progress variable mean reaction rate that governs the combustion process, which is captured by the Bray–Moss–Libby model.
