CFD simulation of classroom aerosol transmission: source and project details
| Research overview |
This guide helps M.Tech students set up a numerical study of indoor air quality and aerosol behavior. It follows a 2025 study that uses Computational Fluid Dynamics (CFD) to test five different ventilation setups in a classroom. The guide walks you through building three‑dimensional, time‑dependent simulations that run for 210 seconds. The simulations use an Unsteady Reynolds‑Averaged Navier‑Stokes (U‑RANS) method together with an RNG k‑epsilon turbulence model. To model how particles move with the air, the approach adds a Discrete Phase Model (DPM) that combines Eulerian and Lagrangian techniques. The numerical model is very accurate, showing only a 1.08 % relative error when compared with Duguid’s experimental data.
Students will study how changing ventilation design—especially the Opening Area Ratio (OAR)—affects aerosol spread. The reference work found that an OAR of 1.16 % gave the best result, leaving just 101 of 4600 particles (1.2 %) inside the room. The resource also offers step‑by‑step help for setting up multiphase flow models, defining boundary conditions, and running parametric studies aimed at reducing airborne transmission in closed public spaces.

Project or research direction
This is a source-backed research starting point, not a tested, ready-made student project. Any implementation requires independent feasibility, safety and results verification.
Possible tools or components to evaluate
CFD Software (ANSYS Fluent or OpenFOAM), CAD Modeling Tools, Post-Processing Visualization Software
Suggested verification steps
- Read the cited paper and check which methods, parameters and results it actually reports.
- Define a measurable project objective and list equipment or software you can access.
- Validate the proposed approach independently before claiming results, working code or experimental success.
Implementation ideas above are planning suggestions, not claims that the cited researchers built or tested those exact extensions.
