Lagrangian Multi-Phase-> Spray Injection with Atomization

I set the parcel number to 1.2e+06,and set up a co-ordinate(Cylinderical).Is the O point of the co-ordinate is the place of injector? But how to set the direction of the spray?

And when I solve my problem,every step there are no C12H26 in the domain and the percentage of O2 and N2 keep the same.

Cud Any1 tell me how to set the parameters of Spray injector? Thx in advance!

1) Direction of spray must be along Z axis.You have to rotate local cylindrical coordinate system appropriately. 2)How have you specified C12H26? Have you set initial conditions for air, molecular properties etc. correctly? You have to specify additional scalars for air (O2, N2).
