Default Reversed flow using Pressure inlet and pressure outlet

Hy everyone,
I want to simulate a Poiseuille flow in a 2D pipe, so i decided to use a pressure inlet, where i imposed the total pressure, and a pressure outlet, where is set static gauge pressure to be 0 . I also used the k-espilon model. As i initialize my solution based on the pressure inlet, i need to impose also the inlet gauge static pressure, and as i have no velocity at the inlet, i set P_sat = P_tot so as to have v=0 at inlet , but when i launch my sims, i get reversed flow in pressure outlet, which is not occurring physically ... Can someone tell me where i'm wrong or how to solve the problem?

Thanks !
