Simulation Bubble Nucleation and Bubble Growth of a Thermal-Bubble Microejector
Published in 2009
The present study investigates simulation model and droplet ejection performance of a thermal-bubble microejector. This model simulates the bubble nucleation and the bubble growth, to predict the droplet ejection process. Specificity, it is achieved by coupling an electric-thermal model and flow model with bubble dynamics equations. The model is validated by comparing prediction results with experimental data. Moreover, the nucleation mechanisms, nucleation temperature and nucleation rate also are studied.
