n the heat transfer analysis of boundary layer flow of viscoelastic fluids many researchers see the variation of temperature of fluid inside the boundary layer with Prandtl number, for which they use prandtl number 0.7, 2 , 3, 4 ..
This is what generally the researchers do..
Currently i am thinking that , such a analysis is wrong because the Prandtl number they use are of air and water and both fluids are not viscoelastic ..
Secondly , i need some examples of viscoelastic fluids with the correspoding values of Prandtl number.
