Numerical simulation of electrospray in the cone-jet mode
Résumé
We present a robust and computationally efficient numerical scheme for simulating steady electrohydrodynamic
atomization processes (electrospray). The main simplification assumed in this
scheme is that all the free electrical charges are distributed over the interface. Comparison of the
results with those calculated with a Volume-of-Fluid method showed that the numerical scheme
presented here accurately describes the flow pattern within the entire liquid domain. Experiments
were performed to partially validate the numerical predictions. The simulations reproduced accurately
the experimental shape of the liquid cone-jet, providing correct values of the emitted electric
current even for configurations very close to the cone-jet stability limit.
