TL;DR: In this article, the effects of thermally grown oxide swelling, creep, and interfacial roughness were taken into account, and the effect of the interfacial cracking on top coat cracking and their mutual interaction were investigated using the cohesive zone model.

TL;DR: In this paper, a two-dimensional periodical model considering the microstructures in ceramic top coat (TC) is built to study the cracking behavior in the TC of APS TBCs penetrated by CMAS during the cooling process.

TL;DR: In this article, the leakage flow through two labyrinth seals, e.g. the interlocking seal and the stepped seal, was numerically investigated, and in-depth understanding of the fluid flow through the labyrinth seals was obtained by employing Fluid Dynamics (CFD) and k − ǫ turbulence model, which resulted in a potential wealth of information like the streamline pattern, velocity vector field, and distribution of turbulent kinetic energy and static pressure.

TL;DR: In this article, a numerical study of the thermal-mechanical behavior of the TBC-film cooling system under operating conditions was conducted, and the effect of radiation heat transfer was considered.

TL;DR: In this article, the role of the internal oxides in interfacial morphology and residual stress was investigated in air plasma sprayed (APS) thermal barrier coating (TBC) samples with double-layered HVOF NiCoCrAlY bond coats.
