Hello everyone,

I am fairly new to ANSYS fluent, and I am in need of assistance or guidance. My current project is to model a stagnant liquid in a pipe 1.25W by 6.65L axisymmetrical (image below). Inside the pipe is a bubbler (gas inlet) of .06m Width. An image of the mesh is attaching to this thread.

The liquid inside the pipe is a mixture of fuel-salt and liquid xenon. The bubbler will purge helium gas into the pipe so that it will absorb the liquid xenon and leave at the outlet. The Viscous model is set for RNG, k-epsilon, Scalable Wall, and Mixture. The operating temperature is 750k and with a pressure of 1.34atm referenced at the outlet. I have reduced the time step to .001 and have played with the relaxation values. What advice or direction would you give me to obtain a convergence so that I can review the simulation?
