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

diamondx will become famous soon enough
that's a tough simulation !! are you beginner ? if yes you need to start by the tutorials, this includes combustion (evaporating of liquid fuel) and multiphase too (you have water and air) ignore the copper body first. you have to start by simple simulation first and take it to next level when you succeed in each steps...
Good luck...
