2D axisymmetric mass flow rate for the plain orifice atomizer
Hello All,
I have a 3D case setup injecting liquid fuel with a certain mass flow rate. I have now reduced the geometry to 2D and to half by using axisymmetry. My question is will the mass flow rate of the injector in this case be reduced by half? In the fluent 6.3 user guid on page 22-112 under point properties for single injections, it states under mass flow rate that in axisymmetric problems the mass flow rate is defined per 2pi radians. Any idea what this means? Thanks! Jimmy |
this means you 3d and 2d axisymetric mass flow rate is same

2d axisymmetric mass flow rate for plain orifice atomizer
Hi, and thanks for responding to my post. I want to know whether the same mass flow in 3D case is what is injected for the 2D axisymmetric case? I have tried injecting the same mass but i am getting a higher mass fraction for my fuel than i was getting when i inject the same mass of fuel in the 3D case.
Any suggestion would be helpful. Thanks! Jimmy |
