About This Lesson
- In this project, the quantitative distribution of human exhaled particles in a ventilated room is simulated using ANSYS Fluent software, based on the methodology from Zhijian Liu’s study.
- The 3-D geometry and mesh were created with user-provided files and consist of 547,820 elements.
- The simulation accounts for steady-state flow conditions and transitions to solve energy and DPM equations transiently.
- Airflow dynamics and heat transfer are analyzed using the ideal gas equation to address density variations due to temperature changes.
- The fan’s operation is modeled through a polynomial pressure jump function.
