injection in Combustion problem
 

I am working on combustion of Diesel Oil. There is a cylindrical(560mm dia.) combustor. At inlet of combustor there is a spray of LDO(Light Diesel Oil) from nozzle of 0.8 mm dia with air inlet from blower.

For analysis, can I take "Injection" of single 0.8mm for the combustion problem?? I have not define any fuel inlet face. just air inlet face has been created in the grid. is it ok?? Then How to start combustion??

Thanks

You can set up your injection using the DPM approach. You can specify where you want the injection to take place, either from a surface or a point injection. TO start combustion you need to patch an area of the flow to initiate combustion. You do this after you have initialized the solution. Pacth a temperature around 2000 K and you should be ok.

Dont forget to follow the combustion laws and set the correct parameters in the materials pannel.
