wedge cells pridicting high T-KE why?

shan

Dear Friends,

I am running Afterburner combustion problem.Total cells size is 2 million with extended domain (followed by CD nozzle,mach 1.6 around) of ambience.I took 60 degree scetor and did the mesh on prostar block meshing.At the axis model has wedge cells and it creates convergence problem while running the analysis.High turbulent KE (1e+5) is pridicted exactly at wedge cells.mass and enthalpy convergence is very slow compared to momentom convergence.my question is,

1.How far wedge cell affects the mass and momenom convergence and final results like total pressure loss etc.?

Thanks in advance
