Abstract

In this study, we examine the behavior of a propane diffusion flame with air in a burner; the computational investigations are achieved for each case employing the Fluent package. The graphs generated illustrate the influence of flow parameters, the effects of the oxygen percentage in the air, and the effects of the equivalence ratio on the entropy generation, the temperature gradients, and the Bejan number. The obtained results show that incorporation of hydrogen with propane reduced both temperature and carbon monoxide emission.

摘要

在本研究中，我们考察了燃烧器中丙烷与空气扩散火焰的行为；针对每种情况，使用Fluent软件包进行了计算研究。生成的图表展示了流动参数的影响、空气中氧气百分比的影响以及当量比对熵产、温度梯度和贝詹数的影响。所得结果表明，丙烷中加入氢气可降低温度和一氧化碳排放。
