Dear friends,

I am working on modeling and simulation of high-velocity oxy-fuel (HVOF) thermal spray process with Kerosene as liquid fuel in workbench Ansys Fluent. I am interested in calculating the velocity and temperature profiles of exhaust combustion products into the atmosphere. The things I have are stated below:

Fuel= Kerosene (C12H22) mass flow rate = 0.00625 kg/s
Oxygen= mass slow rate = 0.02125 kg/s

The combustion process takes place inside the combustion chamber of HVOF spray gun with fuel and oxygen.

C10H20+15O2 - 10CO2+10H2O

The body of Gun is made of copper and liquid cooled to keep it at 50 degrees. The exhaust gases emerged from 8 inch long barrel into open atmosphere. Ignore the powder injection in attached image.

Can anybody tell me how to proceed in steps. Please tell me which model I should go for ? Please find the attached image of HVOF spray gun

Good luck... __________________ Regards, New to ICEM CFD, try this document --> https://goo.gl/NEbygB Ali
