摘要：The combustion is modeled using one-step reaction mechanism assuming complete conversion of the fuel to CO2 and H2O.This analysis illustrates the important role of the heat capacity in the prediction of peak flame temperature.The use of a constant Cp results in a significant over-prediction of the peak temperature.The average exit temperature at the outlet is also over-predicted.This over-prediction of the flame temperature can be corrected by a more realistic model for the temperature and composition dependence of the heat capacity.While the variable Cp solution produces dramatic improvements in the predicted results, further improvements are possible by considering additional models and features available in Fluent.
