 note = {[Abstract] It is known that small quantities of surfactant additives can greatly reduce the friction factors during the flow of a heat transfer medium. This is because the generation of turbulent vortices is suppressed by the formation of rod-like micelles, and the flow remains laminar in the high Reynolds number range. However, the values of the heat transfer coefficients decrease during flow laminarization. The research objective is to examine heat transfer enhancement effects by air injection. This paper presents an experimental investigation on the heat transfer and flow characteristics in an air-surfactant solution two-phase flow through a vertical tube. The air was injected through the porous metal. In this condition, the flow pattern of two-phase flow was bubbly flow which contains many fine bubbles in any flow rate. The bubble diameter was changed by using different types of porous metal. In every condition of air injection, heat transfer coefficients were enhanced drastically with air injection. However, the effects depend on the diameter of bubbles. The heat transfer coefficients was Increased as the diameter of bubbles decreases. This result means that the bulk concentration of rod-like micelles in a surfactant solution in bubbly flow was reduced because micelle was concentrated on the surface of bubbles., application/pdf},
