I'm new to calculating the unsteady two-phase flow, and now I'm trying to implement the SIMPLE algorithm based on the article
"Comparison Of Drift-flux And Multi-fluid Approaches To Modeling Of Multiphase Flow In Oil And Gas Wells"

I clearly discretized the equations. How correct and accurate is that? Draft with formulas attached. He also attached the obtained results, where the blue graph is mine, and the orange graph obtained with OLGA, at t = 300 seconds.

What corrections should be made to achieve the right decision?

Also how correctly to account for the time? Since only the step appears in the formulas, I do not understand how to properly conduct the time counter.

I'm just learning and ready for any criticism and help, thank you for your time!
