A novel membrane resonant droplet ejector (MRDE) for viscous industrial liquids is proposed in the paper. In MRDE, a vibrating nozzle is built to generate micro-droplets and the nozzle clogging could be reduced. The droplet jetting mechanism is studied by a three-dimensional (3D) lattice Boltzmann (LB) model. The effects of voltage amplitude and driving frequency on droplet volume and velocity are explored. Experimental Results show that low-viscosity water and viscous glycol could be jetted stably in parameters of 30 V/16 kHz and 60 V/20 kHz, respectively. Moreover, the droplet jetting of MRDE and in-situ observation is set up to analysis the droplet jetting characteristics. The critical thresholds for MRDE are 9.340 ≤ R e ≤ 17.65 , 3.653 ≤ W e ≤ 8.846 and 0.014 ≤ o h ≤ 0.411 , which has a wider printable range than traditional piezoelectric printheads. With the compact structure, MRDE is easy of integration for mass industrial applications compared with the pneumatic and needle-based ejectors. • A novel membrane resonant droplet ejector (MRDE) is proposed for viscous industrial liquid. • The vibrating nozzle could reduce nozzle clogging. • The critical thresholds for MRDE is presented which extends the traditional printable range. • MRDE is easy of integration for mass industrial applications.
