I am new for combustion simulation. In Fluent tutorial, there is an example "Modeling Evaporating Liquid Spray". I want to developed it to a combustion. Yes, I want to see the combustion. I am using liquid fuel Ch3OH as in the example. After I set the problem as the example, I am using PDF method as in the coal combustion tutorial example. I followed the prePDF method in the tutorial. After 1000 iteration, it does not burn at all. Can anybody helps?

I would like to know (1) Does my PDF file have problem? Who can give me a pdf for other fuel so I can continue the example? (2) Should I use other method than PDF method? (3) If PDF can, what problem could I have?

Thank you. drop me a mail if you can: (I use @+@ to prevent email robot. Pls take out +@ when you send me mail).

Also, do You use DPM Model for particle injection? If so, make sure you have droplet set under particle type in injections panel, default inert particle does not burn.
