1) initial temp = 220. Above boiling point of (pure) water. Is this what you expect because of the liquid density?
Yes.
2) kettle vol = 15x3.14xr^2 = 4250 in^3 = 18.40 gals vice 15 gal in the spreadsheet. Is it not filled all the way under normal mixes?
This is definitely an entry error in...
However, especially since this appears to be a home-project versus something you're doing for work, you might want to invest in some books in home brewing.
I have a few home brew texts. I just want to learn something new and apply it to my problem.
I do this myself (never simulated it though)...
Unfortunately I don't have any book on heat transfer.
Do you have the names of the equations or could maybe type them up for me?
I'd rather not have to buy a textbook, but do you have any recommendations off of Amazon? Thanks.
That's right. Sorry I assumed that calculation was for the flow of the cooling liquid, not the hot wort.
I stir the wort from time to time, but it mostly moves on it's own from convection. It's quite pretty to watch actually :) Will the convection induces a perfect laminar flow in this way...
That's the thing... I'm not sure :) I'm getting my information from:
http://en.wikipedia.org/wiki/Nusselt_number
I assumed forced convection in laminar fully developed pipe flow, but this is probably not the case. Should I be using the Dittus-Boelter equation to solve for the Nusselt number?
Hello,
I'm an EE with no thermo background, but have done some reading. I need to build an immersion chiller (http://www.homebrewtalk.com/wiki/index.php/Immersion_Chiller#Immersion_chillers) to cool my wort for homebrewing. The chiller sits in the boiling wort and the intake connects to a sink...
