Using an engineering analysis approach to accurately estimate the heat release rate of a heavy goods vehicle (HGV) fire in a road tunnel is a challenging task. The present study attempts to use a simple calculation approach and the Fire Dynamic Simulator 6.0.7 (FDS) to estimate the fire growth and peak heat release rate based on the results from one of the Singapore Fire Tests Programme. This article presents and discusses the two different modelling approaches; 1) Heat release rate per unit area coupled with the ignition temperature method, and 2) Kinetic Pyrolysis method that can be used in FDS to estimate the growth phase and peak heat release rate of a HGV fire. Although the air velocity in the fire test was 3 m/s, different air velocities and ignition locations were simulated to examine the impact of varying the air velocity and its effect on the development of HGV fire in a road tunnel.
