all rad and fan stuff here

insert blinking RED LIGHT

the sim is fun, but there is a train wreck dead ahead

where is the data going to come from upon which to base any calculation ?

you absolutely cannot have 'users' plugging in CFM values, they are WAY too ignorant
what will be used is the fan's spec'd free flow value which has no bearing on its output pushing through a rad
- if a semblance of accuracy is required the specific P-Q data must be pulled from the fan's graph
THEN matched to the rad's flow resistance

the air and liquid flow resistances are tedious to obtain, but not really so difficult
-> the dissipation is hugely difficult, and complex

note that in my rad testing (article) I 'quantified' only the liquid side dT
AND I used a air/coolant temp differential of 10°C (should have been 5°C to reflect a 'good' system)
but the lower the differential, the less capability the rad will have

properly done there would be an energy balance calc looking at both sides
- understand the problem: the quantities we are dealing with make such temp quantifications extremely difficult (= prone to error)

what needs to be derived are "dissipation/in³" values as a function of air velocity; for each 'type' of rad core

jeez, someone better start writing grant proposals
is there a research PhD in the house ??
