“…This test case serves as a validation for the phase change model in several articles [1,8,14,54]. Indeed, when the temperature at the wall is much larger than the saturation temperature, a persistent layer of vapor forms and remains between the wall and the water.…”

“…Alternatively, interface capturing methods consist in a implicit definition of the interface. A volume fraction (Volume-Of-Fluid) or a signed distance function (Level Set) is convected using a transport equation [6][7][8][9][10][11][12][13][14][15][16][17][18].…”

“…Jet impingement is widely used in cooling system about thermal equipment or industrial process that operate high temperature because it has high cooling capability in impingement region [1] and it is a rapid cooling system [2]. For example, it has been used for microelectronic components that are operated on extreme temperature condition [3][4][5], and quenching of steel plates during the manufacturing process that needs to control temperature on materials [6][7][8]. In the field of electronic cooling, air impinging has been contributed to high heat flux device.…”

The effect of adding air into water jet flow for heat transfer enhancement was investigated for submerged impinging jet. The Reynolds number of water jet was fixed at ReL = 2.4x10 4 , the nozzle to impingement surface distance was also fixed at L = 2D, and the volumetric fraction was varied from = 0.0 to 0.7. The heat transfer measurement was studied using an infrared thermal imaging camera. The flow behavior of bubbly jet was observed by a high-speed camera. The result showed that the heat transfer of the bubbly jet for all cases were higher than the water jet case. The average Nusselt number on surface was continuously increased for increasing volumetric fraction = 0.0 to 0.2. It was found that the volumetric fraction at = 0.2 gave the maximum heat transfer enhancement about 33% compared to case of water jet. But the increase of volumetric fraction in range = 0.2 to 0.7 decreased the average Nusselt number.

“…As a common class of thermodynamic problems, quenching phenomena research has been widely applied in engineering area. There exist some typical researches including the flow, thermal properties, and its working mechanism of an object in heat associated with quenching phenomena [1,2], the forced convection quench of hot sheets in super-cooled liquid [3], the quench process speed-up, and its quench characteristics in porous interface processing [4,5]. In recent years, more and more scholars concern quenching problem built on parabolic equations [6][7][8][9][10], in which the authors depended on the different parabolic equations to analyze corresponding quench features.…”

Quenching characteristics based on the two-dimensional (2D) nonlinear unsteady convection-reaction-diffusion equation are creatively researched. The study develops a 2D compact finite difference scheme constructed by using the first and the second central difference operator to approximate the first-order and the second-order spatial derivative, Taylor series expansion rule, and the reminder-correction method to approximate the three-order and the four-order spatial derivative, respectively, and the forward difference scheme to discretize temporal derivative, which brings the accuracy resulted meanwhile. Influences of degenerate parameter, convection parameter, and the length of the rectangle definition domain on quenching behaviors and performances of special quenching cases are discussed and evaluated by using the proposed scheme on the adaptive grid. It is feasible for the paper to offer potential support for further research on quenching problem.
