I made a small drawing to depict what I want to do:
Sometimes a small drawing can help to reactivate the brain after a hot and long day... [glasses] So it's going the be the first way, using ref. temperature 0°C.
@LittleInch: Trust me, I am. :) In my "real" storage, which is deployed in 7 real...
@IRStuff:
The storage has several pipe connectors, so that there is water in- and out-flowing. Thus the mass may change, depending on the density.
Considering the SOC: Ok, thanks. So should I just take the basic equation without reference state: Q = sum(T * cp(T) * rho(T) * V_cell) ?
Yes, that may be true. But let's consider it as part of a high-resolution thermal simulation (yeah, errors apply here as well), so the resolution of the sensor array is very high.
And introducing an additional 2% error is not applicable.
Besides the simulation the gradient can be also measured...
Hi!
@desertfox:
For my calculations, cp and rho are quite significant. A 2% error is already quite much. Furthermore in my "real" calculations even larger spreads are possible, thus errors are even larger.
And this calculation has to be implemented in an optimization dealing with energy flows...
Hi everyone!
I'm new here and just registered since I thought this might be a good place to ask.
I'm an aeronautics engineer specialized in the fields of thermodynamics and fluid mechanics, currently working as a researchers.
This is also the reason why I feel quite stupid having to ask this...
