Combined Effects of Temperature and Reynolds Number on Heat Transfer Characteristics of a Cationic Surfactant Solution
The heat transfer characteristics of a dilute cationic surfactant solution, CTAC/NaSal aqueous solution, were experimentally investigated in a fully developed two-dimensional water channel flow at different temperatures ranging from 15°C to 60°C and at different mass concentrations, namely, 75, 100,...

| description | The heat transfer characteristics of a dilute cationic surfactant solution, CTAC/NaSal aqueous solution, were experimentally investigated in a fully developed two-dimensional water channel flow at different temperatures ranging from 15°C to 60°C and at different mass concentrations, namely, 75, 100, and 200 ppm. The magnitudes of the maximum achievable heat transfer reduction (HTR) at the above three different surfactant concentrations are all about 90%. The cationic surfactant solution showed a great heat transfer reduction phenomenon, which was greatly affected by concentration, temperature, and Reynolds number. It was supposed that temperature and shear stress are two kinds of energy applied on the surfactant microstructure, which can be helpful to the surfactant network formation or dissociation depending on their values. |
