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

There are some loose estimates in the article:

A general bioheat transfer model based on the theory of porous media
A. Nakayama, F. Kuwahara

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

Specific surface area and interfacial area density are the same thing. Most porous media literature will say specific surface area, while CFX prefers the term interfacial area density.
