“…The characters of Carbopol, CMC and Glucosesyrup solutions on the heat transfer in turbulent pipe flow were studied and the results indicated that transition to turbulence for non-Newtonian fluids was delayed, the shear thinning and the yield stress enhanced the stability of the flow [2]. The article [3]demonstrated the consistency between the drag reduction behavior and the viscoelastic behavior of polymer solutions and the relationship between viscoelasticity and concentration through viscosity measurements.…”

Abstract. The drag reduction effects of a non-Newtonian fluid (CMC aqueous solution with 50-1000wppm) in a sinusoidal wavy-walled tube were investigated experimentally in the Reynolds numbers range from 25 to 360. Based on the pressure drop method, drag reduction was measured and the maximum drag reduction achieved was 38% using 700wppm. It was found that in the end of the laminar flow region the CMC polymer solutions display more distinct drag reduction than that in turbulent flow region. Besides, the effect of rheological parameters on drag reduction has been discussed.

“…The increasing slip coefficient resulted in an increase of the local Nusselt number, and this effect was enhanced as the power law index increased. Peixinho et al [16] experimentally studied the forced convection heat transfer of non-Newtonian flow in transitional periodic pipes. The results showed that the non-Newtonian behavior stabilized the flow, so the critical Reynolds number increased with shear-thinning.…”

Flow characteristics and heat transfer performances of carboxymethyl cellulose (CMC) aqueous solutions in the microchannels with flow control structures were investigated in this study. The researches were carried out with various flow rates and concentrations of the CMC aqueous solutions. The results reveal that the pin-finned microchannel has the most uniform temperature distribution on the structured walls, and the average temperature on the structured wall reaches the minimum value in cylinder-ribbed microchannels at the same flow rate and CMC concentration. Moreover, the protruded microchannel obtains the minimum relative Fanning friction factor f /f 0 , while, the maximum f /f 0 is observed in the cylinder-ribbed microchannel. Furthermore, the minimum f /f 0 is reached at the cases with CMC2000, and also, the relative Nusselt number Nu/Nu 0 of CMC2000 cases is larger than that of other cases in the four structured microchannels. Therefore, 2000 ppm is the recommended concentration of CMC aqueous solutions in all the cases with different flow rates and flow control structures. Pin-finned microchannels are preferred in low flow rate cases, while, V-grooved microchannels have the minimum relative entropy generation S'/S 0 ' and best thermal performance TP at CMC2000 in high flow rates.
