Aerosol Formation in Electrospray Ionization Using a Microfluidic Emitter

This work presents simulation of aerosol formation in electrospray ionization (ESI) using a carbon fiber (CF) emitter. The model predicts droplet fission and trajectories of the droplets in a steady medium, within a monodisperse EHD spray in a Lagrangian framework. The droplet fission is simulated based on the principle of minimum free energy and droplet trajectories are predicted using Lagrangian single-droplet tracking method. The numerical model is validated by comparing model predictions with experimental results. The aerosol formation process using the CF emitter is simulated and results are presented and discussed.
