  • Effect of Surfactant Additive on Heat Transfer Inside Tubes

抄録

In surfactant solution (TTAB+NaSal), the pipe friction factor and heat transfer coefficients were investigated. The straight circular tube of D=5.0mm in diameter and L=2800mm in total length was used. In the drag reduction flow, in order to break micelle structures and to promote heat transfer, the "micelle breaker" was installed in the upper stream of the testsection. As a result of the experiments, in surfactant solution (1000ppm), compared with the case of water, the friction factor decreased 75% in Re=11000,and NuPr^<-1/3> decreased 75%. However, installation of the micelle breaker increased NuPr^<-1/3> by 1.8 times compared with the case where it does not install.
