Simple Heat Transfer

Simple Heat Transfer

Simple Heat Transfer

(OP)
Hi,

I'm looking for simple equations govering gas flow through a duct with heat transfer.  I'm looking for pressure and velocity with varying geometry and heat transfer rates.  Nothing too complex at this stage.

Thanks in advance,

Gordon.

RE: Simple Heat Transfer

Try your Heat Transfer textbook, for starters.  See what ASHRAE sells secondly.

RE: Simple Heat Transfer

To me it seems like you are trying to oversimplify something.

Best regards

RE: Simple Heat Transfer

Simple Heat Transfer?  That's a wishful misnomer.  The only thing simple in heat transfer is the Fourier equation - until it's basis and ramifications are explained.  Although there is nothing simple about it, a lot can be gleaned from reading - like JStephen recommends.

I wonder how many engineering students have taken heat transfer courses as electives to "fatten up" their grade point average.  These are the courses I'd love to see physcology & political science students taking.  I'm sorry; I'm being mean.  These courses are man-eaters and I should be kinder and more compassionate.

Good luck on the reading.

RE: Simple Heat Transfer

Misnomer?  I thought the word was oxymoron.

Great comment, Art.

grkerrigan,

I would suggest you refer to The Dynamics and Thermodynamics of Compressible Fluid Flow by Ascher H. Shapiro.  Chapter 7 in Volume I is Flow in Ducts with Heating or Cooling.

Good luck,
Latexman

grkerrigan-
Looks like you just joined the forum!  Welcome aboard!  Based on the replies to your wide open question, it looks like you'll have to dig for the information (which people should do before they post to the forum).

Thank you Latexman for that response.  I have heard of Shapiro before and will look the book up.

I haven't worked with heat transfer or thermo for about 10 years now and all my text books are on the other side of the globe in storage, aka not much use.  I have zero hard copy resources to work with at this stage.

I have been accussed of trying to oversimplify things before, the thing is I usually end up finding what I'm looking for.  I've come across too many people trying to big note themselves by trying to make out how hard things are by overcomplicating them (steps down from soap box).
