Jet Impingement Boiling

1993
Publisher Summary Impinging liquid jets have found usage in many industrial applications, in both submerged (liquid-into-liquid) and free-surface (liquid-into-gas) arrangements. Because of the attractiveness of jet impingement cooling for high-heat-flux applications, numerous studies have been performed for both single- and two-phase conditions. This

Measurement of two-dimensional heat transfer and flow characteristics of an impinging sweeping jet

International Journal of Heat and Mass Transfer, 2019
This study experimentally explores the two-dimensional heat transfer characteristics of an impinging sweeping jet generated from a feedback–channel-type fluidic oscillator. The results were compared to those of a steady square jet. A phosphor thermometry

Impinging Circular Turbulent Jets

Journal of the Hydraulics Division, 1974
The normal impingement of turbulent circular jets on smooth walls is studied both experimentally and analytically. This type of flow can be divided into three distinct flow regions: the free-jet region; the impingement region; and the wall-jet region. The impingement region is the most important.

Incompressible impinging jet flow with gravity

Calculus of Variations and Partial Differential Equations, 2018
In this paper, we investigate steady two-dimensional free-surface flows of an inviscid and incompressible fluid emerging from a nozzle, falling under gravity and impinging onto a horizontal wall. More precisely, for any given atmosphere pressure $$p_{atm}

Heat transfer of a sweeping jet impinging at narrow spacings

Experimental Thermal and Fluid Science, 2019
Sweeping jet, featuring with temporally continuous and spatially oscillating flow, has attracted a large amount of attention. In the present study, the heat transfer and flow characteristics of a sweeping jet impinging at narrow spacings were ...

Multiple jet impingement cooling

Journal of Thermophysics and Heat Transfer, 1993
Experiments were performed to study the effect of nozzle rotation, flow rate, degrees of subcooling, number of jets, and velocity on the heat flux in jet impingement cooling using deionized distilled water. The heat flux is a strong function of the flow rate and degree of subcooling, attaining a maximum value of the order of 600 W/cm at the highest ...

Impinging sweeping jet and convective heat transfer on curved surfaces

International Journal of Heat and Fluid Flow, 2019
The application of an impinging sweeping jet, which oscillates periodically with a large angle, to convective heat transfer has received attention owing to its capability to provide a more spatially uniform and enhanced heat removal rate when compared to

Nozzle external geometry as a boundary condition for the azimuthal mode selection in an impinging underexpanded jet

Journal of Fluid Mechanics, 2019
The role of the external boundary conditions of the nozzle surface on the azimuthal mode selection of impinging supersonic jets is demonstrated for the first time.

Flow structure and heat transfer of a sweeping jet impinging on a flat wall

International Journal of Heat and Mass Transfer, 2018
While an impinging jet has been widely investigated because of its remarkable convective heat transfer performance, the impingement of a sweeping jet which undergoes periodic oscillation has drawn little interest.
