An Experimental Study of Amplitude and Frequency Effects upon a Pulsating Jet

Journal of Fluid Science and Technology, 2009
Pulsating jets are very common and useful in various industrial aspects. However, they have some different basic characteristics from steady jets. In this research, the authors reveal both the frequency and the amplitude effects of pulsations on a jet ...

Characterization of Defect Distribution in an Additively Manufactured AlSi10Mg as a Function of Processing Parameters and Correlations with Extreme Value Statistics

Advanced Engineering Materials, EarlyView.
Predicting extreme defects in additive manufacturing remains a key challenge limiting its structural reliability. This study proposes a statistical framework that integrates Extreme Value Theory with advanced process indicators to explore defect–process relationships and improve the estimation of critical defect sizes. The approach provides a basis for

Inlet device with double exponential profile distributor for indoor air dispensation

Selected Scientific Papers: Journal of Civil Engineering, 2019
This paper presents a device for introducing air inside a room with the novelty of double-exponential profile of the distributor. This allows entering the rooms of large quantities of blow-in air with low velocities, with the result of possible use in ...

Flow Structure of a Coaxial Circular Jet with Axisymmetric and Helical Instability Modes

Journal of Fluid Science and Technology, 2011
The flow structures in a coaxial jet with axisymmetric and helical instability modes for a comparatively low Reynolds number were investigated. The flow visualization and the measurements of velocities were carried out in an open water tank. In addition,

Measurements of jet quenching with semi-inclusive charged jet distributions in $Au+Au$ collisions at $\sqrt{s_{NN}}$=200 GeV

, 2015
We report measurements of jet quenching in $Au+Au$ collisions at $\sqrt{s_{NN}}$=200 GeV, based on the semi-inclusive distribution of reconstructed charged particle jets recoiling from a high $p_T$ hadron trigger.

Evaluation of the Potential of Laser Shock Peening Compared with Cold Expansion for Improving Fatigue Resistance of Riveted Lap Joints of Aerospace Grade 7175 Al Alloy

Advanced Engineering Materials, EarlyView.
This study investigates laser shock peening for enhancing fatigue performance of riveted aerospace aluminum joints. A comparative approach with cold expansion combines fatigue testing and synchrotron X‐ray methods. Integrating mechanical testing with residual stress and strain characterization provides insights into how different treatments affect the ...

Jet Modules

Canadian Journal of Mathematics, 2007
AbstractIn this paper we classify indecomposable modules for the Lie algebra of vector fields on a torus that admit a compatible action of the algebra of functions. An important family of suchmodules is given by spaces of jets of tensor fields.

Linear Stochastic Estimation of the Velocity Field from a High-Bypass Nozzle with and without Mixing Devices

Journal of Fluid Science and Technology, 2011
Linear Stochastic estimation (LSE) is employed to compare the large-scale structure of a jet exhausted through a coaxial nozzle configuration with and without mixing devices on the coaxial stream.

Next-to-Leading Order QCD Corrections to Jet Cross Sections and Jet Rates in Deeply Inelastic Electron Proton Scattering

, 1993
Jet cross sections in deeply inelastic scattering in the case of transverse photon exchange for the production of (1+1) and (2+1) jets are calculated in next-to-leading order QCD (here the `+1' stands for the target remnant jet, which is included in the ...
