Pharma Cleanroom Aerosol CFD Simulation
Budget: $30 – $250 AUD
I need a detailed CFD study that shows how bioaerosols behave inside a pharmaceutical cleanroom when ventilation layouts, healthcare-worker movement, and sliding-door cycles all interact. My main priority is solid evidence on bioaerosol containment, so the results must clearly report concentration levels and spread patterns at critical zones (work benches, return grilles, door gap, operator breathing height).
Scope of work
• Build a 3-D model of the room, insert the proposed ventilation schemes (balanced-return systems) and replicate the door and human movement sequences exactly as provided in the layout drawings and timing chart I will share.
• Implement a transient solver with an appropriate turbulence model, add a discrete phase (DPM) for the bioaerosol, and release particles from the specified source terms.
• Run separate cases for each ventilation scenario and movement cycle, then post-process contour plots, vectors, time-history graphs, and short animations that highlight areas of accumulation and leakage.
• Provide a concise technical report interpreting the findings and recommending design or operating changes that improve containment.
Deliverables
1. All solver/mesh setup files (ready to reopen in ANSYS Fluent, CFX, or OpenFOAM).
2. Raw result files plus exported plots and MP4/GIF animations.
3. PDF report with methodology, grid-independence note, validation check, discussion, and actionable recommendations.
Acceptance criteria
• Mesh independence demonstrated with at least two grid densities.
• Mass balance error <1 %.
• Reported particle concentration and spread maps for each scenario, delivered in a format I can insert directly into our internal presentation.
I am comfortable with Fluent, CFX, or OpenFOAM—use whichever gives you the most confidence, as long as the files open on my end without licensing issues. Please note any third-party UDFs or custom OpenFOAM libraries you employ so I can compile them locally.
Timetable and milestone structure are flexible; outline your preferred run schedule with an estimate of simulation hours so I can allocate compute resources in advance.
