| Summary: | Nowadays, the application of Thermal Barrier Coating (TBC) has been
increased dramatically in various industries due to these coatings can extend part
life of components by reducing thermal fatigue. TBC is commonly used to protect
machine components from the high-temperature surroundings, a condition which
commonly occurs in nuclear reactors, turbine blade in airplanes, etc. TBC serves
to maximize the utilization of component’s lives by insulating the components
from high temperatures exposure. One way to create an appreciable temperature
difference between the components and the coating surface is by determining the
optimum thickness of the TBC that usually done by experiments. However, conducting
experiments are expensive and time-consuming. Therefore, a computer
simulation is needed to overcome these problems. This study aims to develop a
computer simulation based on finite element method. Furthermore, we present the
analytical solution of a simple mathematical TBCs model derived from Laplace
transformation and Residue theorem. Then, we test the accuracy of the simulation
by comparing the simulation results with the analytical solution. The result shows
that both of the simulations based on finite element method and the exact solution
are in agreement which confirm the accuracy of the model/simulation |
