Please help with liquid fuel combustion modelling

tom

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?
