non premixed combustion

deepthishan · February 1, 2013, 03:34

hi,
I am having a problem when simulating non premixed modelling of swirl flows. The temperature contour is oscillating when modelling stoichiometric ratios away from 1.Can anybody tell the reason behind this?what can be done to overcome this?

Yes, using Fluent only

Do you know why the temperature peak in temperature contour keeps oscillating?I am using K-e model,non premixed,eqb,adiabatic with two air swirlers coaxially placed with a fuel inlet inbetween.
