This thesis involves the study of the dynamics of upward propelled droplets using the experimental method. An experimental setup was designed consisting of a pneumatic cylinder, an acrylic glass plate, a compressor, control valves, and tubing. A droplet is placed on an acrylic plate which is actuated to move up and down using a pressurized pneumatic cylinder. When the pressure is applied, the plate undergoes a sudden linear upward motion and launches the droplet into air whose behaviour is then recorded using a high-speed camera. We developed a MATLAB® code for image processing and using the code, we try to understand the behaviour of the droplet in terms of shape oscillation, aspect ratio, etc. by varying the size of the droplet and propulsive force. The results of this experimental setup agree well with earlier simulation results within our research group.
