Impact of P-1 radiation model on simulated free jet flame characteristics of gaseous fuels: CFD with PDF approach

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