medical inhalers
 

Hi to all colleagues is there anyone out there involved in modelling flow from the metered dose inhaler devices(MDI's), if so can you tell me what approach you are using to model the flow at the exit of the nozzel. At present I am simply modelling the fluid in my case air exiting the nozzel as a compressible flow, but it does not give good enough results. I would be grateful for your suggestions. many thanks vahid

(1).What is your computational domain? (2).How does such device work? Is it something like a spray can?
