Inhalation drug delivery has seen a swift rise in the use of dry powder inhalers (DPIs) to treat chronic respiratory conditions. However, universal adoption DPIs been restrained due their low efficiencies and significant losses mouth-throat region. Aerosol efficiency is closely related fluid-dynamics characteristics inhalation flow generated from devices, which turn are influenced by device des...

Abstract In the present study, an existing test rig at Institute of Thermal Turbomachinery (ITS), Karlsruhe Technology (KIT), designed for generic film cooling studies is adopted to accommodate time-resolved stereoscopic particle image velocimetry (SPIV) measurements. Through a similarity analysis, geometry scaled by factor about 20. Operating conditions hot gas and air inlet exit can be impose...
