      hi users,nnI 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 usenvelocity specification method : componentsnreference frame : absolutencoordinate system : cylindrical ( radial, tangential, axial)nradial = 0ntangential = 19naxial = 32.nam I correctly specifying boundary conditions?n

      That sounds about right. You should be able to plot these velocities and verify them visually. Just an FYI.nThanks.nKarthikn
