Looking for OLD ASME article on Flashing Steam 3

[TechsMechs]

I have been looking everywhere (especially at ASME.org) for how to get a copy of "The Flow of a Flashing Mixture of Water and Steam through Pipes" by M.W. Benjamin and J.G. Miller from the "Transactions of the ASME" 64, from October of 1942. I know it is often referenced for blowdown vessel operations and sizing for two-phase flow, but there are some basis questions I have that can really only be resolved by looking at the paper.

Does anyone have a PDF copy of this one that they could share? I would greatly appreciate it.

(Thanks in advance)

I have found a copy of the thecnical paper you asked for. Unfortunately I can´t send you until the next week.

Thank you very much, casflo. I look forward to it.

TechsMechs, I attach the Benjamin and Miller´s paper.
Regards.

Also, see the hardbound copy of the ASME steam tables, circa 1985, they have blowdown pipe sizing charts in the printed steam tables - in the form of choked 2 phase flow.

Prior to 1995, there was also an ABMA or nat'l board document for sizing blowdown tanks and interconnected piping- but it was strickly only valvid for single steam drum units- it became outdated after the onrush of 3 drum combined cycle HRSG's were built.

You can probably get a copy of the paper from the Linda Hall Library for a very reasonable cost.

Techs....

What is your ultimate goal here..??

Perhaps, to size and purchase a flashing vessel..??/

Or to undersatnd the thermodynamics of the operation.

MJCronin,

Actually, a little of both. With the NBIC NB-27 publication, we found a few errors and technical limitations, which davefitz illuminated above. I like the publication quite a bit, but we had conditions not covered in the graphs and curve-fit equations in NB-27, so I wanted to see some of the original basis documents on solving for the mass flow-rates of the two-phase mixture. We talked to several tank vendors in parallel, plus reviewed some other literature, and now have a method we are comfortable with.

I'm quite thankful for casflo's contribution and the other information from davefitz for opening up this topic a little more. I hate the de facto response of "give it to a vendor that specializes in this", because we've had the unfortunate "luck" of finding ones that say they can do something--like adequately size blowdown tanks--but end up doing something that is against our client's expectations.
