Effect of Spacing Between the Double Pool Fires on the Flame Emissiviy and Temperature

The emissivity of the double pool fires (DPF) is helpful in radiative heat transfer calculations, fundamental research, and numerical simulations. In this work, emissivity measurements are performed on 0.1 m gasoline circular DPF using infrared camera. Along with emissivity measurements, the mass burning rate (MBR), flame merging probability, and height are also measured. The results show that MBR, flame merging probability, height, and emissivity increase with a decrease in non-dimensional separation distance (S/D). The variation of emissivity along the flame height is also studied and realised that it decreases with the increase in flame height.
