Al,

Sorry my notes don't ID the source, I understand what your saying and you may be correct, there could be a whole host of variables, however I found it interesting enough to record the conclusion.

Matter of fact I still find it hard to believe, but I have since found people that have found a minor inclined Rad to be less desirable than vertical, so feel that it may hold true for any installation - 55* does sound a lot doesn't it.

Thomas,

Nice research.

I found my notes on inclined radiators, they state

1. 0-20/30* will decrease cooling and increase drag.

2. Over 30* things improve.

3. At approx 55* cooling effectiveness is 30% greater than non-inclined rads

and drag is less by 20%.

George; do you have the source for that info? It may be a good idea to verify this information. I don’t recall the specifics; but what I do recall is that the conclusion was configuration dependant, and should not be taken as generally applicable. Sorry, but I don’t remember what the factors were; maybe something about the configuration of the core.

Or maybe my memory just isn’t right. Worth checking.
