LES-CMC simulations of different auto-ignition regimes of hydrogen in a hot turbulent air Co-flow [PDF]

open access: yes, 2013
Large-Eddy Simulation (LES) results in combination with first-order Conditional Moment Closure (CMC) are presented for a hydrogen jet, diluted with nitrogen, issued into a turbulent co-flowing hot air stream.

Numerical Investigation of Performance Enhancement of the S809 Airfoil and Phase VI Wind Turbine Blade Using Co-Flow Jet Technology

open access: yesEnergies, 2021
Making full use of wind energy can effectively alleviate the global energy shortage and environment contamination problems. Nevertheless, how to significantly improve the performance of the wind turbine airfoil and blade is a crucial issue.

Stability and Liftoff of a N2-in-H2 Jet Flame in a Vitiated Co-flow at Atmospheric Pressure

open access: yesEurasian Chemico-Technological Journal, 2014
The stability and liftoff characteristics of a nitrogen (N2) diluted hydrogen (H2) jet flame in a vitiated co-flow are investigated experimentally with particular attention focused on regimes where multiple stabilization mechanisms are active ...

Bubble size prediction in co-flowing streams [PDF]

open access: yes, 2011
In this paper, the size of bubbles formed through the breakup of a gaseous jet in a co-axial microfluidic device is derived. The gaseous jet surrounded by a co-flowing liquid stream breaks up into monodisperse microbubbles and the size of the bubbles is ...

Propeller-Induced Jet Impact on Vegetated Flow Fields: Complex Coupled Effect towards the Velocity Profile

open access: yesApplied Sciences, 2023
The failure of swirling ship propellers in marine environments can lead to huge repair costs. One of the main causes of such failure is when propellers tangle with vegetation, especially in shallow flow environments like ports, harbours, or shipyards. In

Simulation of hydrogen auto-ignition in a turbulent co-flow of heated air with LES and CMC approach [PDF]

open access: yes, 2011
Large-Eddy Simulations (LES) with the first order Conditional Moment Closure (CMC) approach of a nitrogen-diluted hydrogen jet, igniting in a turbulent co-flowing hot air stream, are discussed. A detailed mechanism (nine species, 19 reactions) is used to

CFD Analysis of Co Flow Jet Airfoil

open access: yesIndian Journal of Science and Technology, 2016
The performance of airfoils can be improved by using flow control techniques like Co Flow Jet (CFJ) technique. Many of the control flow techniques are applied only near leading or trailing edge, whereas the CFJ technique is applied on most of the suction surface.

Precessing Jet and Large Dust Grains in the V380 Ori NE Star-forming Region [PDF]

open access: yes, 2017
The V380 Ori NE bipolar outflow was imaged in the SiO and CO J = 1 - 0 lines, and dense cores in L1641 were observed in the 2.0-0.89 mm continuum. The highly collimated SiO jet shows point-symmetric oscillation patterns in both position and velocity ...

Numerical Predictions of Uniform CO2 Corrosion in Complex Fluid Domains Using Low Reynolds Number Models

open access: yesMetals, 2018
To get the knowledge of local corrosion, thinning is useful for developing targeted inspection plans for pipe components in the oil/gas industry. Aiming at this object, this work presents a computer fluid dynamics (CFD) method to predict CO2 aqueous ...

Intrinsic Differences in the Inner Jets of High- and Low-Optically Polarized Radio Quasars [PDF]

open access: yes, 2000
A significant fraction of compact radio-loud quasars display most of the characteristics of relativistically beamed, high-optical polarization blazars, yet are weakly polarized in the optical regime.
