摘要:
采用k-ε湍流模型和SAMPLE迭代求解方法进行数值仿真,通过对模型温度、压力、边界条件等参数的设置,初步研究大空间内汽油燃烧火灾的气体生成物、残余物、环境温度分布等与汽油混合分数之间的关系.仿真结果表明:在不同的汽油混合分数下,由于空间内的氧含量有限,使得燃烧的化学反应不同,相应的,各生产量、产生的热量和温度的分布也不同.
Abstract:
In this paper, k-ε turbulence model and the SAMPLE iterative solution method is used for numerical simulation. By setting the parameters of model temperature, pressure and boundary conditions, the relationship between gas product, residue, environmental temperature distribution of the burning gasoline fire in large space and gasoline mixture fraction has been preliminarily studied. Simulation results show that in different gasoline mixing fraction, due to the oxygen content limitation within the space, the combustion chemical reaction is different. Accordingly, the production, heat generation and temperature distribution are also different.
