Group injection distribution
 
Hello,

I am doing a combustion simulation in a gas turbine combustor. I have tried the 2D coal.cas tutorial which uses a Rosin-Rammler distribution. But when I check the diameter distribution, it shows an flat, even distribution. Also when I implemented the group injection in my 3D case, it shows the same instead of a Rosin-Rammler distribution.

Why is this?

thanks for the time taken in replying

Regards

David

Hi

It should work. Try it again and take care you have given all details in Injection Panel: Location, mean dia, spread parameter, etc.

Hi,

thanks for your response.

but no it's not working, I have tried times and again and the results keep changing even though i put the same data.

Does anyone have any idea of what is wrong in my case?

thanks
