Design
Dry Powder Inhalers
• Accuracy: Multiphase flow, steady and transient
flow, particle–flow interaction models, particle–
particle, and particle–wall interactions
• Optimizing device design for pressure drop and
particle size distribution
• Powder dosing/capsule emptying
• Particle de-agglomeration
• Device delivery efficiency (particle deposition)
• Understand impact of inhaler design on
performance
• Predict capsule emptying efficiency
• Predict powder de-agglomeration efficiency
• Reduced time to market
• Improved reliability
