Airflow simulation testing using CFD
Challenge
Use the energy from the user’s inhaled breath to evacuate powder from a capsule and deliver it to the deep lung.
Approach
Computational fluid dynamics (CFD) were used to simulate the airflow and particles in the inhaler before designing the prototype and testing it in the laboratory.
Outcome
The inhaler device was able to evacuate and deagglomerate the powder into respirable particles, while reducing the likelihood of powder deposition in the user’s mouth.
