Hello,

I examined different swirl ratios in dual-fuel combustion. According to literature, increasing swirl ratio increases the heat losses, however, my results showed that increasing swirl decreases the heat losses. I used Orouk and Amsden heat transfer model. I appreciate if you could help me. I'm gonna change the heat transfer model to Han and Reitz and see the results probably the previous model is not able to consider the swirl motion.

Regards,
Amin.

Usually swirl enhances combustion. Better combustion has higher temperature which can have more heat transfer. The correlation between swirl and combustion is not that simple in simulation. It depends on the combustion models and the mechanism when you use SAGE.

Thanks,
