Hi, i am new to software, i am working how spray nozzle will effect the temperature and pressure inside pool type reactor in 2D. I don’t know how i will specify mfix to disperse water flow at inlet(coming from nozzle). also i added all the IC and BC and necessary info and ran my simulation but i don’t see my simulation time increasing.
Your help will be appreciated. Thank You

A few comments:
- You did not define any pressure outlet
- The k-epsilon IC and BC values don’t look right. If you don’t know what values you should use, then you probably don’t need to use a turbulence model.
- You have 3 inlets defined at the top, but they overlap, is this as intended?
- When troubleshooting, it is easier to start with a coarse mesh
- With incompressible fluid, you will usually get better convergence if you increase the number of gas pressure and momentum equations in the linear equation solver (Numerics>Linear Solver tab)
My suggestion is to coarsen to mesh, define a pressure outlet, turn off k-epsilon and increase the number of equations in the linear solver.
