inhaler
 

Hi guys I am working on a project in which I have to model an inhaler for asthmatic patient. The inhaler works in the following way. First the capsule is inserted in the inhaler and then the capsule is broken by twisting the cap. The powder from the capsule falls into the inhaler which is later on inhaled from the opening provided just to the side of the capsule. I am interested in the flow of the powder within the inhaler Now guys I need advice on how to begin my simulation. Is this a multiphase problem or I can do this with particle tracking.

Hope I am able to make my problem clear if not I can be even more elaborative. Regards wilson
