Numerical approach for axisymmetric piezoceramic goemetries towards fluid control applications

In this work, a finite element model has been developed to analyse axisymmetricpiezoceramic actuators with arbitrary internal poling. The finite element methodology is verified by demonstrating favourable agreement between the numerical results obtained in this study with the results published for an inkjet printer application. In addition, the design of a piezoceramic nozzle is investigated with both single-layer and stacked axisymmetric piezoceramic geometries. Such piezoceramic nozzles and orifices can be effectively employed in various sensitive fluid control applications. (Original abstract - amended)
