Particle-Droplet-PBS: Population balance software for simulation of particle-induced droplet breakup in spray flame synthesis and suspension spray combustion

The software ‘Particle Droplet Population Balance Simulation’ (Particle-Droplet-PBS) simulates the time of particle-shell formation and particle growth in burning spray droplets. Application examples are provided to demonstrate how the code can be used to incorporate a variety of particles, precursor chemicals and solvents. The software solves the population balance equations for particle coagulation and nucleation, while applying an adaptive grid method requiring only two cells per droplet. Thus, the computation time is drastically reduced. This enables users without access to high-performance work stations to run droplet simulations in a timely manner, making it a valuable tool for research and process engineering.
