This paper presents an experimental study on the burning rates and thermal feedback of pool fires under wind effects and sidewall restrictions in a tunnel. A series of pool fire tests were ... the different restriction boundaries. The results indicate that the burning rates of the two fire locations both increase ... and finally increase slowly. For lower wind speeds, the burning rates of sidewall fires are slightly higher than ... reverses for larger wind speeds. These variations of the burning rates are mainly attributed to the evolution of ...
