thermal expansivity of blood

kmgraju · November 28, 2012, 04:24

Dear friends
I could not find thermal expansivity value for human blood.
But I read Bossinesq model. I know density value which is 1060 kg/m^3

How do I approach the problem
Please help me

Thank you

Regards
Govind

Is there any buoyancy driven flow in blood? I don't know what you are modeling but I would assume blood is usually very close to isothermal and movement due to pressure dominates the flow?

In the body blood is essentially isothermal. Buoyancy shouldn't be important unless you are working with some unique application I am not thinking of.
