The following equation was developed by Dr. J. J. Salamone for calculating the fibs coefficient of heat transfer to non-Newtonian suspensions in turbulent flow (Re 50,000 - 200.000) inside of pipes:
hD/Kf = 0.131 (DVbPb/ub)0.62 (D/Ds)0.05 (Cs/Cf)0.35 (Cfub/Kf)0.72 (Ks/Kf)0.05
This equation was investigated to determine its validity over the lower turbulent regions of the Reynolds number (10,000 - 70,000), and to test the exponents of the various components.
Equipment was constructed similar to that used in the original investigation with added improvements from which it was hoped to gain more accuracy.
The results of the correlated data showed the following equation to be valid:
hD/Kf = 0.348 (DVbPb/ub)0.7 (Ds/D)0.152 (C/Cs)0.35 (Cfub)/Kf)0.72(Ks/Kf)0.08
The original investigation also showed that the effective thermal conductivity varied with velocity and reached some limiting value at full turbulence, which was corroborated by this investigation.
The calculated data further substantiated that certain properties of the slurry utilized in this equation such as bulk velocity, bulk density, and bulk viscosity, heretofore not used in equations, could be used for designing heat transfer equipment for non-Newtonian suspensions.
