“…They have easily integrated the eddy dissipation model with a two-phase Eulerian-Lagrangian formulation of the fuel spray and evaporation. Other examples of using the eddy dissipation model in turbulent combustion modeling of gas turbines can be found in [17][18][19][20][21][22].…”

“…Hydrogen enrichment is a potential technique for improving natural gas combustion systems for power generation and industrial applications. The addition of hydrogen enables the combustion system to be operated at very lean conditions which improves the fuel economy and overall system efficiency [1,2,3]. However, the combustion of hydrogen causes significant temperature rise in some regions of the flame [4].…”

A set of numerical simulations were conducted to estimate the change in entropy generation in swirl stabilized CH4/air flames due to H2 addition to the fuel. A robust finite volume computational model solving the Reynolds Averaged Navier Stokes with a first order turbulence closure and laminar flamelet combustion model was used to compute the flow and energy fields in the flame. Hydrogen enrichment resulted in an increase in the entropy generation rate of the flame. Such increase was attributed to the increase in heat transfer irreversibilities due to flame temperature rise.

Biogas has a great potential to be applied for heat and power generation throughout the world due to its availability from various resources. However, one of the most important barriers of biogas utilization development is its low calorific value. In order to increase the performance of biogas in industrial application, hydrogen enriched biogas could be substituted. In this paper a set of numerical simulations were conducted to estimate the variation of entropy generation in hydrogen enriched biogas flames due to hydrogen addition to the fuel. Reynolds Averaged Navier Stokes with a second order turbulence closure and laminar flamelet combustion model was applied to compute energy fields and flow in the flame. It was found that hydrogen enrichment resulted in an augmentation in the entropy generation rate of the biogas conventional flame. Such increase could be attributed to the increase in irreversibilities due to biogas flame temperature rise.
