CFD Ventilation Design for Underground Parking
Budget: $30 – $250 USD
I am finalising the ventilation concept for an underground parking facility and need a full CFD study that leads directly to an optimised jet-fan layout. At the moment I only have basic architectural sketches, so your first task will be to translate those outlines into a clean 3-D model suitable for simulation (AutoCAD, Revit or similar—use whichever you are fastest with).
The objectives are threefold:
• Prove that fresh air and smoke are cleared efficiently throughout the entire volume.
• Identify a fan configuration that minimises power draw without compromising performance.
• Document that the design satisfies all applicable local safety codes for enclosed car parks.
Please run steady-state and, if necessary, transient scenarios in Fluent, FDS, OpenFOAM or an equivalent solver you are comfortable with. I expect clear visualisations of velocity, pressure, temperature and contaminant concentration, plus a concise explanation of any design iterations you make along the way.
Deliverables
1. Native CFD files + exportable geometry.
2. A PDF report summarising methodology, key plots, compliance notes and energy calculations.
3. Final jet-fan placement drawings with specifications (diameter, flow rate, orientation, mounting height).
4. A short hand-over call or video walk-through so my MEP contractor can pick up the model without friction.
Acceptance will be based on stable convergence, meeting the target air-change rate and demonstrating code compliance in the worst-case smoke scenario. If you have recent underground-parking examples, feel free to mention them when you bid—seeing comparable work will speed up selection.
