DEM-CFD collaboration helps to control solid particle trajectories from an inhaler to the human airways

Webinar: Analyzing Particles in Fluid Flow: A Life-Saving Example

With recent health crises and attention to aerosol particles, there is a need for a high-fidelity predicting tool to answer public health questions. In designing devices for inhaled medication, accuracy and reliability are critical objectives and severely change the outcome. One example of these devices is dry powder inhalers, which is becoming more and more popular since it is easier to store in dry, remote, or dangerous regions for an extended time.

Medication delivery can be vastly improved with well-designed decisions. The interaction between the active pharmaceutical ingredient, its carrier, and the inhaler to deliver the correct dosage in the respiratory system remains a challenge, however.

In this webinar, you will learn how combining computational fluid dynamics (CFD) with discrete element modeling (DEM) is essential to design a dry powder inhaler (DPI).
