Like electrip_flip, I also interested in some specific references.
I am only aware of two from which this can be concluded :-
(1) the work of Suresh Garimella :- http://widget.ecn.purdue.edu/~eclweb...ht_results.xls from http://widget.ecn.purdue.edu/~eclweb/jet_benchmark/
(2) Calculating the "h" profiles using the Flomerics calculator http://www.coolingzone.com/Content/D...as/fcalc10.htm (referred to by leejsmith)
I am keen to add to my info pool.

An old example of the parameters I use at 20C..

My interpreation of the consequences for the "best case"(probably no interference beteen Jets) on a flat surface of 9 Jet array compared to a Single Jet are shown in my post in the original Volenti thread http://<br /> <a href="http://forum...eadid=4650</a>
