CFD turbulent fluid, discussion about pressure gradient

[QUOTE="Navin A S, post: 6887314, member: 568390"] The decrease in pressure after the sudden expansion is due to the loss of kinetic energy associated with the rapid decrease in velocity. This decrease in velocity causes a decrease in pressure as per Bernoulli's equation. As the flow continues, the velocity and pressure increase again due to the turbulent mixing of the flow, which helps to recover some of the lost kinetic energy. The pressure then increases again until it reaches its original value at the outlet. [/QUOTE]
