“…Several single-jet studies in the literature experienced a saturation temperature overshoot, where wall temperatures were required to be much higher than the fluid saturation temperature to initiate boiling [9,45]. In the current study, the interaction of neighboring jets on the impingement surface may explain the absence of any overshoot or boiling hysteresis.…”

This work presents the single-and two-phase results of a parametric study investigating the performance of oblique jet arrays impinging at 45 deg on a 3.63 cm square copper heater surface using R-245fa. It was found that the parameters that most impact heat transfer changed as the system progressed from single-to two-phase flow behavior. The single-phase peiformance was governed by the jet geometry and the volumetric flow rate, while in the two-phase region, heat transfer performance was primarily affected by the fluid conditions and the heat flux applied. A single-phase correlation was developed to capture the low heat flux response, and the two-phase results were well-correlated by a pool boiling correlation. A new general correlation for jet impingement heat transfer with phase change is presented combining these correlations. Critical heat flux (CHF) data were compared with literature correlations and a new correlation was developed for arrays of boiling jets.

“…In the flow field of a single impinging jet, boiling behavior is most often observed beginning away from the stagnation region of the jet, often at a hydraulic jump or heater boundary, extending inward toward the jet [45,46]. Critical heat flux is believed to follow a similar pattern [9].…”

“…To develop the jet impingement CHF correlation, the number of jet impingement CHF data points considered from the studies by Cardenas and Narayanan [14][15][16][17][18] is 46 (excluding pool boiling cases). Table 4 presents uncertainty estimates for measured and determined variables [23], Data reproducibility was studied by performing repetitions and replications of experiments and it was found that CHF varied between 4% and 6% [18].…”

“…Table 1 presents a summary of 12 distinct jet impingement CHF correlations that have been proposed in literature and their respective range of parameters. The paper uses data published by this group on CHF for subatmospheric pressure submerged jet impingement boiling using de-ionized water and atmospheric pressure data using FC-72 [14][15][16][17][18]. In general, fluid properties, such as liquid and vapor densities, latent heat of vaporization, and surface tension, have always been shown to be relevant.…”

A G e n e ra liz e d C ritic a l H e a t F lu x C o rre la tio n fo r S u b m e rg e d and F ree S u rfa c e J e t Im p in g e m e n t B o ilin gA critical heat flux (CHF) correlation is developed fo r je t impingement boiling o f a single round je t on aflat circular surface. The correlation is valid fo r submerged jets as well as fo r free surface jets with Reynolds numbers (Re) between 4000 and 60,000. Data fo r the correlation are obtained from an extensive experimental study o f submerged je t impinge ment boiling performed by the authors with water at subatmospheric pressures and with FC-72 at atmospheric pressure. Additional experimental data from a free surface jet study are also incorporated to include the effect o f variation in surface diameter relative to a fixed nozzle diameter, additional working fluids (water and R-113 both at atmos pheric pressure), and jet configuration. The range o f parameters considered include Re from 0 (pool boiling) to 60,000, je t diameter to capillary length scale ratios (d/L c) rang ing from 0.44 to 5.50, surface diameter to capillary length scale ratios (dsILc) ranging from 4.47 to 38.42, and liquid-to-vapor density ratios from 119 to 8502. The proposed correlation is built on the framework o f a forced convective CHF model. Using this cor relation, 95% o f the experimental CHF je t impingement data can be predicted within ±22% error. The corresponding average absolute error and the maximum absolute error are 8% and 36%, respectively, over the range o f parameters considered. ObjectivesThe objective of the present work is to address the aforemen tioned deficiencies in literature for predicting jet impingement boiling CHF. A correlation stemming from a physical hydrody namic instability model of Haramura and Katto [2] is used to pre dict CHF over a wide range of fluidic and geometrical parameters.
