Air entrainment in hydraulic jumps in pipelines
Air entrainment in hydraulic jumps in pipelines
(OP)
Hi - I am looking for some information on how to calculate the amount of air entrained by the formation of a hydraulic jump in a fairly large (DN2700) pipeline.
Thanks!
Thanks!

If there was no air in contact with the water at the jump, any vapor space would be filled with 100% water vapor which would collapse back to liquid with the next sufficient increase in pressure or reduction in temperature. In that case you must calculate the depth of liquid flow in the pipeline for the slope and flowrate in the segment, the vapor space being the remaining volume.
If there was air contact at the jump, I think you would have to know the quantity being supplied. Again the entrained air downstream being the difference between that and the solution limit.
