Quantifying Blowing Ratio for Shaped Cooling Holes

Journal of Turbomachinery, 2017
Effusion cooling has been a popular technology integrated into the design of gas turbine combustor liners. A staggering amount of research was completed that quantified performance with respect to operating conditions and cooling hole geometric properties; however, most of these investigations did not address the influence of the manufacturing process ...

Influence of Blow-Up Ratio on Properties of Cellulose Packaging Films by Blow-Extrusion Process

Advanced Materials Research, 2011
The blow-extruded tube-like regeneration cellulose films in different blow-up ratios were prepared by NMMO technology. It was studied the effect of different blow-up ratio on the mechanical and obstructing properties as well as the morphology cross-section of cellulose blown films.

On steady and pulsed low-blowing-ratio transverse jets

Journal of Fluid Mechanics, 2013
AbstractThe present experimental and numerical study focuses on the vortical structures encountered in steady and pulsed low-blowing-ratio transverse jets ($0. 150\leq \mathit{BR}\leq 4. 2$), a configuration hardly discussed in the literature. Under unforced conditions at low blowing ratio, a stable leading-edge shear-layer rollup is identified inside ...
