A model for predicting fluid flow with forming droplet in a microjet fluidic device is described. The model considers the approach of non-linear autoregressive moving average model with exogenous inputs (NARMAX) to analyze the dynamic flow behavior of droplet that can be helpful to design microjet geometry in bionanotechnology application. The study in microjet controls a droplet size that is arrival at nanoliter volumes. The working fluids in experimental measuring process are the solution of gold nanoparticles and oil acid. This study focuses on a real time for droplet behavior with the variety of pressure in the channel. Based on identifying both time and frequency domain models, the behavior of droplet flow could be analyzed in microfluidic on-chip system.
