Effects of design parameters on a multi jet impinging heat transfer
Alexandria Engineering Journal, 2018 The main focus of this work is a synergistic heat transfer analysis of the impinging multi jets. The geometry of the jet holes, arrangement of those holes, density of the jets through spanwise and streamwise directions and type of the confinement are the

Advanced Engineering Materials, EarlyView.This study investigates the fundamental mechanisms of a novel postweld treatment that significantly enhances fatigue performance through engineered residual stress (RS) states. A multiscale approach correlates tensile RS in the nanometallic multilayer coating with corresponding compressive RS in the steel substrate, thereby reducing localized stress ...

Structurally Colored Physically Unclonable Functions with Ultra‐Rich and Stable Encoding Capacity
Advanced Functional Materials, Volume 35, Issue 12, March 18, 2025.This study reports a design strategy for generating bright‐field resolvable physically unclonable functions with extremely rich encoding capacity coupled with outstanding thermal and chemical stability. The optical response emerges from thickness‐dependent structural color formation in ZnO features, which are fabricated by physical vapor deposition ...

Similarity of the concentration field of gas-phase turbulent jets [PDF]
, 1990 This work is an experimental investigation of the turbulent concentration field formed when the nozzle gas from a round, momentum-driven, free turbulent jet mixes with gas entrained from a quiescent reservoir. The measurements, which were made with a non-
