Hi,
I am trying to simulate heat transfer to supercritical pressure water flowing through an annulus with inner wall heated and outer wall adiabatic, using ANSYS FLUENT 14. I am using realizable k-e turbulence model with enhanced wall treatment and SIMPLEC algorithm for pressure velocity coupling. The flow condition is as follows:
mass flux at inlet: 2200 kg/m2.sec
heat flux at inner wall: 2410 kw/m2
operating pressure: 23.5 MPa
inner dia 8mm, outer dia. 10 mm

I am able to run the simulation but it is not getting conversed. The continuity is not conversed.
Can anyone please help me to solve this problem???
