Exploring inhaled air-particle-vapor mixtures in the Human Respiratory System with Ansys Fluent® simulations

Unlock the potential of CFD with this comprehensive tutorial on simulating inhaled air-particle-vapor mixtures in the human respiratory system using Ansys Fluent®, the fluid simulation software, as well as post-processing simulation results using Ansys CFD-Post and Ansys EnSight™, the 

simulation data visualization software. This guide details the step-by-step process of generating research-level meshes for subject-specific airway geometry and setting up advanced simulations to analyze airflow, particle transport, and vapor distribution in the respiratory tract.

Explore the intricacies of airflow dynamics, particle interactions using the Discrete Phase Model (DPM), and species transport via User-Defined Scalars (UDS). Detailed instructions ensure learners grasp the essentials of pre-processing, solver configuration, and post-processing, providing a thorough understanding of the CFD workflow for computational lung aerosol dynamics.

Ideal for researchers, engineers, and healthcare professionals, this tutorial not only enhances CFD simulation skills but also contributes to advancing pulmonary healthcare and occupational safety. Mastering these simulations equips learners to develop targeted drug delivery systems, optimize inhalation therapies, and assess occupational exposure risks.
