AI Thread Summary

The Eulerian view is debated regarding its validity for unsteady flows, with some arguing it only applies to steady flows due to the need for constant velocities at points in the flow domain. However, it is clarified that both Eulerian and Lagrangian descriptions are applicable to unsteady flows. The distinction between steady and unsteady flows does not invalidate either perspective. Therefore, the Eulerian view remains a valid approach for analyzing unsteady flow conditions. Understanding both frameworks is essential for comprehensive fluid dynamics analysis.

Is Eulerian view valid when the flow is unsteady? I think Eulerian view is valid only for steady flows because the points in the flow domain should be with constant velocities.

Thank you.

Neither the Eulerian nor Lagrangian descriptions of a flow field care whether the flow is steady or not. Both are valid for unsteady flows.

Thread 'Query on Isentropic relationships (such as PV^gamma = constant)'

Hi all, I have a question. So from the derivation of the Isentropic process relationship PV^gamma = constant, there is a step dW = PdV, which can only be said for quasi-equilibrium (or reversible) processes. As such I believe PV^gamma = constant (and the family of equations) should not be applicable to just adiabatic processes? Ie, it should be applicable only for adiabatic + reversible = isentropic processes? However, I've seen couple of online notes/books, and...

Thread 'Dry sump pump issue'

I have an engine that uses a dry sump oiling system. The oil collection pan has three AN fittings to use for scavenging. Two of the fittings are approximately on the same level, the third is about 1/2 to 3/4 inch higher than the other two. The system ran for years with no problem using a three stage pump (one pressure and two scavenge stages). The two scavenge stages were connected at times to any two of the three AN fittings on the tank. Recently I tried an upgrade to a four stage pump...
