Thermal conductivity of Newtonian and non-Newtonian liquids
چکیده انگلیسی
In the present paper the results of the experimental studies directed to the correlation between the non-Newtonian fluids rheological behaviour and thermal conductivity taking into account shear rate effect, have been presented. In the experimental tests 3 Newtonian liquids as well as 18 aqueous solutions of polymers, have been used. Experiments were performed at the solutions concentrations ranged from 1000 to 5000 w.ppm and at temperature changed from 299 to 315 K. The shear rate range extended 0≤γ˙≤750 (s−1). For the non-Newtonian aqueous solutions studied the relation of λ=f(T,γ˙) is evident and should be taken into account in all design practices.
