Wpływ aranżacji przepływu powietrza na proces aerozolizacji leków

Resuspension of powder by airflow was investigated experimentally and numerically (CFD). The aerosol emission efficiency and particle size distribution were measured as a function of airflow rate and flow arrangement in a vicinity of the powder layer. The pressure drop values for tested flow configurations were measured. The research results confirmed that aerodynamic conditions had a significant impact on the concentration and particle size distribution of the aerosol produced from powder. These factors determine potential applications of the given resuspension system in medical inhalers.
