I am posting this message on behalf of Craig Potter as Comalco Research
do not have a news feed yet.  Please reply by mail to Craig.

Comalco Rolled products are investigating a strip cooling system on a
Loewy Aluminium strip mill.  I have been given the task to estimate the
heat transfer coefficient for coolant spray onto the moving Aluminium strip 
(<3mm thick, to be cooled from 130 to 50 C, moving at 500 m/min).  We intend
to use Norpar 15 (a exxon petroleum based coolant) as water will stain the
strip.  

I am looking for information on how to estimate the coefficient or if
any one has measured it what it could be (ballpark).  Has anyone used
Norpar 15 for spray cooling before?  Information on water spray cooling
and spray onto steel (such as in steel continuous casting) will be welcome
also as the spray systems are related(?).  I have read some interesting
papers on the subject, but no citations seem to have examinined spray
cooling onto moving Al strip in a production environment.

Thanks.
