Car Parks And Tunnels CFD Analysis

CFD Analysis for Car Parks, Tunnel and Service Roads

Case Study: Kolkata Metro Stations

CFD Smoke Analysis for Road, Metro, and Service Tunnels shall be carried out as per UAE Fire and Life Safety Code, Saudi Arabia Building Code, NFPA 92, NFPA 502, NFPA 103, NFPA 130, Eurocode EN50126, PIARC.

Location:  Kolkata, India

Scope:

The scope of work is to design the smoke ventilation system for the Underground Metro stations and to evaluate the performance of the design using CFD Modelling. Various Fire scenarios were conducted.

A Comparative analysis was done of various design standard like Eurocode EN50126, NFPA 130, SIA etc. was done to arrive at the most suitable standard applicable for Kolkata conditions. Also local building code NBC was studied. NFPA 130 standard was largely used as a design guideline for the fire safety design of subway stations.

The various design options were arrived at with varying capacity and location of smoke exhaust grills as per the guidelines provided in the above stated standards. The CFD simulation was conducted for each configuration. The results of simulation were interpreted and checked whether the required safety standards are met or not.

Parameters Studied: 

  • Smoke concentrations

  • Temperature Profile

  • Visibility Profile

  • Velocity Profile

  • Smoke Simulation Movie

  • Toxicity i.e Carbon Monoxide Concentration

  • Radiant Heat Flux on the walls

Case Study: TAT Mall

The CO contaminant / pollutant  CFD analysis shall be carried out for parking car parks as recommended in ASHRAE Handbook Chapter 16, 2019, California standards 2019 CMC 403.7.2(2), Australian-New Zealand Standards 1668.2-2002.

Case Study: Sofia South Rig Mall

CFD Smoke Analysis for the car parks shall be carried out as per UAE Fire and Life Safety Code, Saudi Arabia Building Code, BS- 7346-7, SFPE, NFPA, Singapore Civil Defense.
