Hi, i am doing my non-premixed engine combustion simulation with ANSYS FLUENT. I have output mass-average absolute pressure, temperature and volume for validation. Although pressure can match the validation but for heat release rate and temperature were so smaller compare to experimental data. Izzit the report type problem and usually what report type will be use for pressure, temperature?, NOx and soot? N with the equation of HRR, i put the absolute pressure in each time step in P, volume in V and change of pressure in each time step and change in volume in each time step and gamma i using 1.4 . I wonder i put the wrong term inside? I am using RNG K-epsilon, there got swirl dominated flow and inside can chg the swirl factor. is the swirl factor same meaning with swirl ratio?
