Looks good: I'll take next week off and leave you in charge in here!   


The lumpy residuals mean the model is slightly transient: the jets will be oscillating slightly which will affect the numerical convergence but not the overall result. Use monitor points to help judge when the model stops changing. I'd also look at the new Fluent Meshing Watertight Geometry workflow: that'll help with quality (usually) as poly cells are both easier and more accurate. 


What boundary conditions did you use?
