Abstract

The temperature profile of horizontally oriented jet flame with square fuel source has rarely been investigated in past years; especially, the effect of fuel portal geometry aspect ratio on temperature distribution of horizontally oriented jet flame has little appeared in the previous literature. In order to study the temperature profile of horizontal jet fire, a numerical simulated code was carried out to simulate horizontal jet fire with square fire source and natural gas as fuel. The fuel jet velocity was varied from 27.5 to 205.8 m/s. The temperature distribution features on horizontal and vertical directions were investigated, and the temperature prediction model was amended. The results show that the temperature is influenced by fuel jet velocity heavily. The heat release rate increases linearly with fuel jet velocity, and the slope is 29.1. The horizontal maximum temperature on orifice centerline direction rises from 304.5 to 614.8 °C with fuel jet velocity increase. The predicted model is modified to apply to horizontal jet fire, and the predictions by amended model agree well with simulated data.
