aravind vashista is on a distinguished road
hi users,

I am simulating a swirl burner which has a central fuel jet and swirling air coming out of the annulus. The central fuel jet has axial velocity = 32 m/s and swirling air has axial and tangential velocity components as 32 m/s and 19 m/s respectively. I use velocity inlet boundary conditions to specify inlet boundary conditions for both fuel and air. For swirling air I use
velocity specification method : components
reference frame : absolute
coordinate system : cylindrical ( radial, tangential, axial)
radial = 0
tangential = 19
axial = 32.
am I correctly specifying boundary conditions?
