14, and a monodisperse droplet generator was used to inject acetone droplet through the flame. PLIF will measure the OH radical and acetone was used to measure the spatial distribution of the fuel vapor and the structure of the flame front. The analysis showed that the droplet crossing strongly...
Various factors, such as the choice of aerosol generator and nonsolvent, control the size distribution and morphology of yttria-stabilized zirconia powder derived from sulfate salts. For instance, acetone produces fused masses, whereas with isopropanol spheres are formed almost exclusively. In ethanol, ...
(Fig.1a, b). The alignment of the droplet generator and electrodes (Fig.1b, c) ensures that the droplet is dispensed into the vicinity of the electrode where it can be successfully trapped by its electric force field. Once the voltage (\({V}_{s}\)) is lowered, the dominant ...
Second, we combined TESLI with pneumatic microvalve-based droplet generator, which to date had demonstrated hundreds of nL-scale droplets per device, but we foresee that TESLI can be flexibly combined with different droplet generators14. In particular, we plan to combine TESLI with our previous ...
As indicated above, droplet generators are currently being designed to produce droplets continuously for relatively long periods such as several weeks or longer, producing billions of droplets. During these operational periods, it is generally not practical to stop and re-start the droplet generator. ...
The experimental setup of the droplet generator is presented in Figure 2. The pressure vessel (b), which contained the continuous phase, was pressurized by a pressurized nitrogen gas cylinder (a) to pump the fluid through the setup. The pressure vessel ensured a pulsation free flow. The volume...
