This study presents a numerical investigation of the aerohydrodynamic interaction between a liquid alternative fuel derived from biomass pyrolysis and airflow inside the combustion chamber of a power generation system. A two-dimensional computational model was developed in COMSOL Multiphysics using the finite element method. The turbulent motion of the airflow supplied to the combustion chamber was described using the Navier-Stokes and continuity equations together with a standard turbulence model, whereas the motion of the biomass pyrolysis liquid droplets was represented using a Lagrangian particle-tracking approach. The computational domain was discretized using free triangular elements. The numerical results demonstrated that optimizing the pyrolysis-liquid injection velocity, droplet diameter, inlet-flow ratio, and outlet-channel configuration can enhance mixing intensity, reduce the fraction of droplets impinging on the chamber walls, and facilitate the efficient organization of the fuel combustion process.
