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 ...

Jets in a Crossflow: Effects of Geometry and Blowing Ratio

Journal of Fluids Engineering, 1999
The flow field characteristics of three different geometries of square jets in a crossflow at various blowing ratios are examined. The geometries considered are: perpendicular, streamwise-inclined, and spanwise-inclined jets. The inclined jets are at a 30 deg angle to the wind tunnel floor.

Effect of Uncertainty in Blowing Ratio on Film Cooling Effectiveness

Volume 3: Gas Turbine Heat Transfer; Transport Phenomena in Materials Processing and Manufacturing; Heat Transfer in Electronic Equipment; Symposium in Honor of Professor Richard Goldstein; Symposium in Honor of Prof. Spalding; Symposium in Honor of Prof. Arthur E. Bergles, 2013
In this study the effect of randomness of blowing ratio on film cooling performance is investigated by combining direct numerical simulations with a stochastic collocation approach. The geometry includes a 35-degree inclined jet with a plenum attached to it. The blowing ratio variations are assumed to have a truncated Gaussian distribution with mean of

The Role of Density Ratio and Blowing Ratio on Film Cooling in a Vane Passage

Volume 4: Heat Transfer, Parts A and B, 2010
Temperature and heat flux measurements have been obtained in a film-cooled, heated fixed-vane cascade. The cascade facility has the capability to deliver high-pressure air through the vane passages at high flow rates (3.5 lbm/s; 1.59 kg/s). Prior to entering the vane test section, pressurized mainstream air has been heated by a natural gas-burning ...
