 December 27, 2012, 10:06 heat transfer coefficient and interfacial area density Data required #1 Senior Member   Govindaraju Join Date: Apr 2010 Posts: 207 Rep Power: 10 I am doing heat and mass transfer analysis when blood flows through a porous artery. I would like to fix interfacial area density between two phases (Fluid phase and solid phase) and heat transfer coefficient Any article or data or any equation that is available? Still I am struggling to find articles . If expert knows please share your knowledge Thank you Govind

Nakayama, F. Kuwahara http://www.demec.ufmg.br/disciplinas...0/artigo03.pdf I think this is relevant to the problem you are solving.

Hi
I have calculated inter facial heat transfer coefficient. But I could not figure out the inter facial area density from the paper as you have suggested. from the paper, is it specific surface area?
In the paper specific surface area = 2*porosity/Radius

Please let me know how to proceed. I struck in this

Thank you

Regards

Govind

Most porous media literature will say specific surface area, while CFX prefers the term interfacial area density.
