Partially stirred reactor model
WebCombustion is one of the most complex phenomena in engineering which requires to deal with turbulent fluid flow, radiative and convective heat transfer, chemical reaction and … WebFor this purpose, a numerical model has been employed which consists of a network of plug flow reactors, counterflow diffusion flame solver and an equilibrium solver for generation of the burned gas. Detailed chemistry and multi-component transport model including Soret and Dufour effects have been used for the calculations.
