NON-STATIONARY HEAT TRANSFER IN A HOLLOW CYLINDER WITH FUNCTIONALLY GRADED MATERIAL PROPERTIES
Piotr Ostrowski, Bohdan Michalak · TU repository (Lodz University of Technology) · 2011
The unidirectional non-stationary heat conduction in a two-phase hol-low cylinder is considered. The conductor is made of two-phase stratified composites and has smooth gradation of effective properties in the ra-dial direction. Therefore, we deal here with a special case of functionally graded materials, FGM. The formulation of mathematical model of the conductor is based on a tolerance averaging approach (TAA). Appli-cation to the non-stationary heat conduction and a comparison of the tolerance model with the asymptotic one is shown. The effect of geome-try and material properties of the conductor on the temperature field is examined. Key words: heat transfer, functionally graded material, tolerance avera-ging approach 1.
