negative static pressure at inlet

hi, I've got a simple geometry: 2 pipes are connected on the same axis. the first one has ø32mm the second one has ø40mm. Massflow is about 1900L/min. (incompressible/ steady state / hydraulic oil) When my solution converged, I compute the drop pressure as the the total pressure difference between inlet (ø32) and outlet (ø40). drop pressure is ok with theoretical solution. BUT when I take a look at he static pressure distribution, the static pressure at the inlet is negative. (and positive at the outlet)
I cannot understand this phenomenon (and I don t trust this solution). Anyone could me explain that? |
