Non-primixed
 

I made PDF file of furnace oil and and read in non-primixed. after that in boundary condtion fuel inlet is given in which mean mixture fraction is 1 and in air inlet there is 0. and initiliztion is given 1000 k with selecting air inlet. but there is no combustion take place. the temp of whole geometry is 1000k . The velocity of the air is 2.04 m/sec in 350 mm dia and fuel is 0.89 m/sec from 9.525 mm dia. The fuel flow rate is 25 liter/ hr. Please help where is the wrong step because there is no combustion take place.
