dP - Two Phase Flow - Fittings

[Assumptions]

Could anyone recommend a reference for estimating the frictional pressure loss in fittings for two phase, gas liquid, flows.

Thanks

That a good one!

Actually i dont think i ever came across this subject. You could do one of wo things:

- Use equivalent lengths as you would for single phase
- Ignore fittings and argue that the uncertaincies in your calculations are such that it dosnt matter. If it would (in single phase) you could add a margin 10, 20, 30...% Whatever seem reasonable.

Best regards

I haven't actually tried it, just found it through a search on the Net. The company I work for has in-house software for predicting pressure drop.
