Project Summary

Building type and location: 200 car capacity car parking building in Jaipur, India

Project goals and objectives: To optimize the jet fans to control smoke and fire due to an 8 MW car burning condition

MaxBrain Technologies role in the project: Service consultancy for CFD simulation using FDS software for Jet Fan Optimization.

Project Challenges

Large building size and complex geometry

Limited data availability for the specific building and fire scenario

Control smoke and fire as per international standards like UAE fire codes, NFC, India, NFPA

Simulation Methodology

Software used: FDS and Smoke View (For Smoke analysis)

Open Foam used for simple Air flow analysis

Simulation time: 1200 seconds as per international standards

Jet fan optimization methodology: Trial and error approach to determine optimal fan location and size

Other simulation parameters: Heat release rate of 8 MW, smoke and heat detectors installed in the building

Results

Key findings: Jet fans were able to effectively control smoke and reduce temperatures, improving occupant safety and reducing property damage

Visualization: Contour plots and animations of temperature and smoke movement in the building

Comparison to design codes: Simulation results met relevant design codes and standards

Impact

Improved fire and smoke control in the building

Reduced property damage and potential loss of life

Potential for future use of optimized jet fans in similar buildings

Lessons Learned

Limited data availability can be a challenge for simulation accuracy

Trial and error optimization approach can be time-consuming and resource-intensive
