Computational Simulation of Entropy Generation in a Combustion Chamber Using a Single Burner

Entropy (Basel). 2018 Dec 3;20(12):922. doi: 10.3390/e20120922.


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 φ 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.
