| Summary: | In this paper, steady heat transfer in multi-layer composite pin fins has been investigated. The appropriate analytical solution for heat conduction in pin fins under the all common thermal boundary conditions has been introduced. The efficiency of pin fins in different boundary conditions of fin's tip has been compared. Placement angle of fibers in each layer as well as a composite material, consisting of fiber and matrix, can be changed layer by layer. In each layer the effects of layers' arrangement based on composite material and fibers' angle has been investigated in details. The impact of environmental and geometric parameters affecting the efficiency of the fin such as heat transfer coefficient, the conductivity of the material used as a filler and fiber, length to diameter ratio of fin thoroughly studied, and the related charts are plotted. |
