Hello, how are you? I am conducting a simulation of a horizontal two-phase separator, which works with oil and gas. I am having a problem because when configuring the outputs as pressure out Flow, after a certain number of iterations, I start having a back flow problem, in which gas enters uncontrollably through the top of the separator, that is, through the gas outlet. I have already configured the operating density, which I set for the gas density. I am unaware of the outlet pressures, which is why I set them to zero for both the upper gas outlet and the lower liquid outlet. I set the inlet as velocity inlet.The Back Flow for the gas was set to 0 with respect to oil. While the Back Flow in the lower pipe with respect to oil was set to 1. I would like to know how to solve the Back Flow problem. This work corresponds to my final degree thesis. Thanks
