摘要：
This work deals with the assessment of optimal working condition of a mesh nebulizer on-demand droplet generation. The purpose of this paper is to introduce a model of vibrating mesh nebulizer to identify optimal working regime from a mechanical point of view. The influence of geometrical parameters and mechanical properties of both the piezoelectric component, vibrating plate and geometry of perforations is investigated and discussed based on an analytical model of stepped plate. This model is validated by 2D-axisymmetric finite element computations. The main trends identified by the model are recovered by the simulation and enable to formulate design rules to maximize the atomization efficiency with respect to a given set of mechanical and geometrical parameters.
