Re: QFin
O dear. Well of course it would. It would also suffer from all the assumptions that have to be made to use a technology that is inherently much fatser than cfd. So, probably applicable to extruded fin heatsinks where flat plate Nu correlations hold, i wouldn't like to guess at the accuracy when applied to impingement type fan sinks, pin fins, heatsinks with developing flows etc.
Dunno, maybe all Qfin users will be wheeled out to contradict the above. I just feel that people should be aware that they never get something for nothing. If you're going to use a part FE conduction solver, part empirical/by pass model then you should be made aware of what the downsides are.
I appreciate the speed and robustness issue and how that lends itself well to optmisation. I personally think full conjugate CFD will be quick enough before too long.
