T reactor simulation - Dont converge - Help plz

I am simulating a circular T-reactor. I modelling half chamber with one injector, and in the middle chamber plane(plane perpendicular to the injector axis) i put a symetry plane.

I am trying to simulating through a Re=300.

I used PISO and SIMPLE scheme, and also change Pressure and Momentum under-relaxation factors, one witg each other.

But my simulation is oscilating and continuity equation dont converge to the residual that i want.

Any tip?
