In order to obtain a fluid with both drag reducing and heat transfer enhanced abilities, we use viscoelastic fluid for drag reducing and stimulate the elastic turbulence for the sake of heat transfer enhancement. To further enhance the heat transfer, carbon powder particles were added to the viscoelastic fluid where Polyacrylamide Ethylene Glycol solution was served as the base fluid. Fluid properties were measured at different solution concentration, shear rate and temperature by the rotary rheometer and thermal conductivity meter including viscosity and heat conductivity coefficients. The results showed that the addition of the carbon powder could significantly change the viscoelastic fluid properties. As for the viscosity, the shear-thinning behavior still exists after adding the carbon powder. Moreover, the heat conductivity coefficients increase about 7.5% after adding the carbon powder and nearly linearly increase with the temperature and volume concentration of the carbon particle.
