  spray cooling
Investigation of heat exchange in the water-spray cooling of high-temperature metal surfaces
      
The spray cooling efficiency is related to the solid temperature decrease as a function of the water mass flux.
      
The dependence of the temperature distribution in FGM on the operating parameters of a double thermal shock method, e.g., a duration of heating, laser beam radius, the rate of a spray cooling, is discussed.
      
Thermal and flow measurements of continuous cryogenic spray cooling
      
The heat transfer removal rate can reach up to 140?W/cm2 for the present nozzle size of dj=0.2 and 0.3?mm, which may enhance the current cryogen spray cooling (CSC) technique that assists laser therapy of dermatoses.

The spray cooling technique has great capacity of heat removal (the critical heat flux density can reach 1 000 W/cm 2) and is increasingly important in many fields. So the investigation of that is very important. The design of heater is related to the quality of the spray cooling experiment, so it is important too.

雾化喷射冷却技术有很高的冷却能力 (临界热流密度可以达到 10 0 0W cm2 ) ,有很好的应用前景[1 ,2 ] 。所以对喷雾冷却的研究有着重要的意义。喷雾冷却实验中加热器的设计关系到整个实验的质量和成败 ,所以加热器的设计显得更加重要

The thickness and behavior of the liquid film on the surface of the wall is the most important to study heat transfer and it mechanism for spray cooling. The paper reported the measurement of the turbulent film under spraying. The turbulent behavior and thickness of the liquid film was measured by a micrometer-scale glide-localizer with oscillograph to check-up if the current pass through the liquid film under spraying at different pressure, and different distance from orifice of the nozzle to the wall. With...

The thickness and behavior of the liquid film on the surface of the wall is the most important to study heat transfer and it mechanism for spray cooling. The paper reported the measurement of the turbulent film under spraying.

With the heat transfer experimental results of the spray cooling, the relationship between the thickness of the liquid film and spray cooling situations was discussed.

The mechanism of heat transfer in spray cooling is complicated, and most theories hitherto are immature. In this paper, according to nozzle spray characteristics, energy and mass balance equations for the liquid film on heated surface were founded, and a half empirical and half analysis model involving the heat dissipation is acquired. The paper presented two heat transfer coefficients: apparent heat transfer coefficient and real heat transfer coefficient. The former is affected by spatial heat dissipation,...

The mechanism of heat transfer in spray cooling is complicated, and most theories hitherto are immature. In this paper, according to nozzle spray characteristics, energy and mass balance equations for the liquid film on heated surface were founded, and a half empirical and half analysis model involving the heat dissipation is acquired. The paper presented two heat transfer coefficients: apparent heat transfer coefficient and real heat transfer coefficient. The former is affected by spatial heat dissipation, while the latter is only related to spray momentum. Later, local heat transfer coefficients were acquired through non-boiling spray cooling experiments, and were compared with the computed value to check the heat transfer coefficient models. As a result, the model was proved to accord with the experimental results.

雾化喷射冷却的换热机理十分复杂,目前其研究还很不成熟。本文从喷射雾滴的特性参数出发,以被冷却表面上形成的喷射液膜为对象,考虑了冷却液体向环境的散热,建立质量、能量守恒方程,得到半经验半解析的雾化喷射换热模型。其中,本文提出真换热系数和显换热系数的概念,认为显换热系数受空间散热影响,而真换热系数只与喷雾动量有关。最后设计了雾化喷射局部换热实验,对模型进行检验,结果表明,该模型能够较好地符合实验所得的换热系数及加热面表面温度沿喷射半径的分布趋势。
