Heat transfer enhancement to a confined impinging synthetic air jet [PDF]

open access: yes, 2013
Heat transfer to confined, un-ducted and ducted impinging synthetic air jets is investigated experimentally. The influence of ducting on the cooling performance of synthetic air jets is of particular interest.

Impinging jets – a short review on strategies for heat transfer enhancement

open access: yesE3S Web of Conferences, 2018
In industrial applications, heat and mass transfer can be considerably increased using impinging jets. A large number of flow phenomena will be generated by the impinging flow, such as: large scale structures, large curvature involving strong shear and ...

Computational study of the application of Al2O3 nanoparticles to forced convection of high-Reynolds swirling jets for engineering cooling processes

open access: yesEngineering Applications of Computational Fluid Mechanics, 2021
Numerical modeling of turbulent impinging swirling jets involve complex flow physics that make their computation still very challenging. Thus, the literature on computational modeling of these nanofluid jets is really scarce, with most works on laminar ...

Presence and properties of acoustic peaks near the nozzle of impinging rocket jets

open access: yesActa Acustica, 2022
The presence and properties of acoustic peaks near the nozzle of impinging rocket jets have been investigated. Four jets at a Mach number of 3.1 impinging on a plate at a distance L = 15r0, 20r0, 25r0 and 30r0 from the nozzle, where r0 is the nozzle ...
