nileshjrane is on a distinguished road

I am trying to simulate the mixing of air and fuel jets in a combustion chamber. I have ran the inviscid incompressible case with icoFoam and pisoFoam. But i wanna use k-eps turbulence simulation. I have specified k eps BCs based on standard formulae. But as soon as switch on RAS model instead of laminar, the solution blows off. The Co number goes very high and crashes in 6-7 steps. I have tried every thing that i could think of. Changing timestep, fv schemes..nthing is helping.

Can some one have a look at my case files and give me any suggestion??? Its very argent...
