Abstract In the current work, by decreasing the sensible heat extraction period and enhancing the internal energy of the evaporating droplet; the high mass flux spray cooling is enhanced with the additional advantages such as attainment of unaltered surface morphology and zero deposition of the additives on the evaporating surface. To achieve the above-mentioned requirements, dextrose is used as an additive in water, which decreases coolant temperature due to heat of dissolution. Furthermore, the exothermic reaction between aqueous glucose and oxygen fulfill the latter requirement. In the current work, the heat transfer analysis clearly depicts enhancement with respect to the heat removal rate obtained in case of cooling by pure water. In addition to the above, the post quenching surface analysis of the heat-treated steel plate assures unaltered surface morphology. The comparison of the current quenching process with the cooling processes reported in the literature clearly asserts its suitability for the fast quenching operation.

使用添加葡萄糖的水在非常高的初始温度下增强喷雾冷却

摘要 目前的工作中，通过降低显热提取周期，提高蒸发液滴的内能；高质量通量喷雾冷却得到增强，并具有其他优势，例如实现未改变的表面形态和添加剂在蒸发表面上的零沉积。为了达到上述要求，在水中使用葡萄糖作为添加剂，由于溶解热而降低冷却剂温度。此外，含水葡萄糖和氧气之间的放热反应满足后一要求。在目前的工作中，传热分析清楚地描述了在纯水冷却的情况下获得的热量去除率的增强。除了以上这些，热处理钢板的淬火后表面分析确保了未改变的表面形态。当前淬火过程与文献中报道的冷却过程的比较清楚地表明其适用于快速淬火操作。
