| Abstract: | On the condition of forced and natural convection, the economical thickness for pipe insulation with variable convective heat transfer coefficient and properties of fluid is investigated analytically and corresponding calculating expressions of economical thickness are obtained. In the meantime, the results are compared with that of constant convective heat transfer coefficient and provided reference for design of pipe insulation. |
