气溶胶发生器已开发和评估的应用程序中的气溶胶浓度和尺寸分布需要定制的特定需求。在该装置中，改进的Wright雾化器产生初级气雾剂，其浓度和在有限程度上的尺寸分布通过选择压降和气液流速比来调节。尺寸分布的进一步修改是通过虚拟和固体板冲击，使特定的气溶胶浓度在特定的尺寸范围内，可以选择作为气溶胶输出。
An aerosol generator has been developed and evaluated for applications where the aerosol concentration and size distribution need to be tailored to specific needs. In this device, a modified Wright nebulizer generates the primary aerosol whose concentration and, to a limited degree, size distribution are adjusted through selection of the pressure drop and the gas-to-liquid flow rate ratio. Further modification of the size distribution is achieved through virtual and solid-plate impaction so that specific aerosol concentration in specific size ranges can be chosen as the aerosol output.
