Abstract |
|
A theoretical study is conducted on the problem of two-dimensional steady-state heat transfer of composites with cylindrically orthotropic fiber with surface effect containing isotropic core. By introducing an appropriate coordinate transformation to convert the governing differential equation into a harmonic one, an analytical solution to the heat flux fields of the cylindrically orthotropic nanofiber reinforced composites is derived based on the surface theory model. Numerical examples provide a better understanding of interesting interaction effects of composite microstructures (geometric and physical parameters of the fiber and core) in heat flux distribution. The radial and circumferential heat flux distributions in the nanocomposites are investigated. The effects of size of the fiber, thermal conductivity of the core and radius of the core on the heat flux distribution are discussed. |
