| Abstract: | This paper analyzes the convective heat transfer enhancement mechanism of latent functionally thermal fluid. By using the effective specific heat capacity model, the influence of each factor affecting the heat transfer enhancement of laminar flow in the tube with constant heat flux is analyzed. In addition, a modification of the conventional Nusselt number definition for internal flow is introduced to describe the degree of heat transfer enhancement for latent functionally thermal fluid more effectively. |
