TL;DR: In this article, a measure of the extra influence on the turbulence which is invariant, fully defined in three dimensions, and unifies rotation and curvature effects is proposed, at the expense of involving higher derivatives than the traditional (non-invariant) terms do.

TL;DR: In this paper, the authors highlight critical R&D needs for advanced TBC systems with a special focus on reduced thermal conductivity and life prediction needs, and highlight the need for reliable and predictable TBC performance.

TL;DR: The chemistry of Ni-based superalloys designed for single crystal gas turbine blades has significantly evolved since the development of the first generation of alloys derived from columnar grained materials as mentioned in this paper.

TL;DR: In this paper, a refined trigonometric shear deformation theory (RTSDT) is presented for the thermoelastic bending analysis of functionally graded sandwich plates, where the displacement components are expressed by trigonometrical series representation through the plate thickness to develop a two-dimensional theory and gives rise to transverse shear stress variation.

TL;DR: In this paper, it is suggested from experimental results that the three-dimensional structure of the separated bubble may be at the origin of the unsteadiness of the shock system, while the frequency of the fluctuations produced by the shock motion are much lower than the characteristic frequencies of turbulence in the incoming boundary layers.
