Ceramic matrix composites are desirable for applications in the thermal protection system of
hypersonic flight vehicles due to their excellent oxidation resistance. However, the service …

The mixing between the coolant and the boundary-layer gas downstream of an injector—for
transpiration/film cooling—has been extensively studied for turbulent flows; however, only a …

The great development of transpiration cooling technology challenges the coolant medium
seriously. In this paper, porous ZrO2–ZrO2 ceramics have been satisfactorily prepared to …

The design of a transpiration-cooled system requires detailed local heat transfer information
on and in the vicinity of the porous injector; however, limited spatially resolved experimental …

This paper presents a novel experimental technique where infrared thermography is
employed to directly measure the surface heat transfer of a transpiration-cooled porous …

Generating a seeping gas film through porous material to cover the downstream wall can
achieve a large-area thermal protection from aerodynamic heating for the windward …

Transpiration cooling have gradually become the lead candidate for thermal protection
technology of hypersonic vehicle also due to its excellent cooling performance. The porous …

This study presents the fabrication possibilities of ultra-high-temperature ceramics of ZrB 2-
30 vol.% SiC and (ZrB 2-HfB 2)-30 vol.% SiC composition using the reaction spark plasma …

An analytical model based on one-dimensional diffusion is proposed to predict the mixing
between the coolant gas and the boundary-layer gas at the wall downstream of a transpiring …

Abstract Unidirectional porous (UP) Si 3 N 4 ceramics are promisingly applied in high-
temperature filtration devices. However, traditional techniques exhibit the drawbacks of high …
