Instability Wave Models of Turbulent Jets from Round and Serrated Nozzles [PDF]
, 2010 In this thesis we study pressure fluctuations associated with large-scale coherent structures in turbulent round and serrated jets. Linear disturbances to the turbulent mean flow of the round jet are modeled via linear stability analysis and the ...

A Non‐Reciprocal Architected Porous Medium
Advanced Functional Materials, EarlyView.ABSTRACT In several fluid flow, energy‐dumping, and energy‐harvesting applications, a dominant flow direction or dominant resistance direction is desirable. In this study, we propose a simple modular geometry that doubles flow resistance in one direction relative to the opposite direction, while maintaining laminar viscous flow.

Experimental aeroacoustics study on jet noise reduction using tangential air injection
, 2011 PhDAircraft jet exhausts are a source of undesirable noise and continue to be an area of investigation driven by increasingly stringent regulation. The noise is produced by the unsteady mixing of the jet with the surrounding air and is dominated by the ...

Jet mixing of water in crude oil pipelines [PDF]
, 1990 The jet mixing of water in crude oil pipelines by single nozzle and multi-nozzle mixers was studied by dividing the mixing domain into to three regions. the penetration. near field and farfield regions.

Jet noise from instability mode interactions [PDF]
, 2008 A nonlinear interaction model is used to study sources of sound in jets. The model uses quadratic interactions of instability modes, which are obtained by solving the linear parabolized stability equations.

Lateral jet interaction with a supersonic crossflow [PDF]
, 2010 A lateral jet in a supersonic crossflow creates a highly complex three-dimensional flow field which is not easily predicted. The aim of this research was to assess the use of a RANS based CFD method to simulate a lateral jet in supersonic crossflow ...

Advanced Functional Materials, EarlyView.This work introduces a swelling‐induced, stress‐assisted water‐soluble PVA tape strategy to transfer‐print nanodiamond quantum‐sensor arrays onto soft, curved biological interfaces. The room‐temperature, water‐triggered process achieves >98% fidelity and residue‐free integration, enabling conformal quantum sensing on contact lenses, neural probes, and ...
