IMPACT OF P-1 RADIATION MODEL ON SIMULATED FREE JET FLAME CHARACTERISTICS OF GASEOUS FUELS: CFD WITH PDF APPROACH

ABSTRACT
Simulation and analysis of a turbulent free jet flame erupting into still air are done using CFD. Using 2-D axisymmetric numerical modelling in ANSYS-FLUENT 14.5. Three distinct kinds of gaseous fuels are used: CH4, CO, and biogas (50% CH4 and 50% CO2). The effects of thermal radiation modelling utilizing the P-1 radiation model on the behavior of a free jet flame are investigated, and the impacts of air temperature and fuel velocity on the flame length are also provided. The findings demonstrated that the radiation modelling did not affect the temperature distribution and flame length for CO and biogas (i.e., lower heating value fuels). Nevertheless, the air temperature and fuel kind considerably impact the flame behavior. While the fuel inlet velocity (i.e., burner power) does not affect the flame length. Additionally, free jet flame velocity and length numerical correlations considering radiation modelling are predicted and presented with allowable errors. A comparison with earlier experimental correlation proved successful, with a maximum error of ±9.4%.
