Abstract (Summary)

The containerless material processing technique is used to test highly reactive materials that cannot be tested in a crucible environment since they react with the container surroundings. There are many containerless processing techniques such as aerodynamic levitation, acoustic levitation, electromagnetic levitation, and electrostatic levitation. This work focuses on the electrostatic levitation system (ESL) present at the University of Louisiana at Lafayette Campus and provides two major contributions to this ESL system. Primarily, the control systems for successfully levitating the sample are designed using Real Time Machine Vision technique. LabVIEW software was used to create logical Programs for image acquisition, image processing, implementing controls algorithm, and for data logging.

Further, the voltage distribution across the electrodes along with the force acting on the sample when subjected to the electric field was analyzed using Finite Element Analysis. The results provide detailed characteristics about the force acting on the sample at different boundary conditions. This result will be helpful in approximating input parameters to the control system.
