Hi friends,
I have the doubt in determining the loss of flow through the numerical simulaiton usinf FLUENT. I took two ways to calculate the results associating with the loss, one is the pressure drop, the other is the integral of dissipation (viscous+turbulence dissipation), but there always exists big difference between the two results. The case is a developed flow in a circular tube, the turbulence model i adopted is standard k-w model, the pressure drop at different Re number were validated against several semi-empricial correlation. |
