Estimating heat transfer coefficient in a forced convection oven

Estimating heat transfer coefficient in a forced convection oven

Estimating heat transfer coefficient in a forced convection oven

(OP)
I would like to estimate heat transfer coefficient in a forced convection oven that is open on both ends.
Oven has multiple heating zones, with zone 1 at 170 degrees C, zone 2 at 180 and zone 3 at 200. This temperatures
may change depending on the batch running. I understand the heat transfer coeffcient should be different for eatch temperature
setting. Where do I start?

RE: Estimating heat transfer coefficient in a forced convection oven

perhaps I'm missing something.

don't we need some more information like:

- what is the creating the "forced" part of the forced oven or do we just assume a uniform temperature in each zone

- is there something moving through the oven? if so, speed, size, surface conditions....

- if stationary then again size, shape, surface conditions (for potential radiation)...

Have Fun!

RE: Estimating heat transfer coefficient in a forced convection oven

It seems to me that the oven described above is similar to a belt oven in which infrared heat may be the predominant form of heat transfer.
