Due to its high heat removal capability and exploitation of latent heat, boiling is considered to be one of the most effective cooling methods in industry. Surface structure and wettability are two factors imposing boiling phenomena. Here, we propose an effective and facile method for surface enhancement via crenarchaeon Sulfolobus Solfataricus P2 bio-coatings. The positive effects of such surfaces of bio-coatings were assessed, and enhancements in heat transfer and cooling were obtained. Visualization was also performed, and bubble dynamics of generated bubbles and vapor columns from the tested surfaces with bio-coatings are here presented. Superior performance in terms of boiling heat transfer and cooling was reached with the use of crenarchaeon Sulfolobus Solfataricus P2 coated surfaces. Thus, this study clearly demonstrates the potential of futuristic surfaces with bio-coatings to achieve substantial energy saving and efficiency.
由于其高散热能力和潜热利用，沸腾被认为是工业中最有效的冷却方法之一。表面结构和润湿性是影响沸腾现象的两个因素。在此，我们提出了一种通过嗜热栖热菌P2生物涂层进行表面增强的有效且简便的方法。评估了这种生物涂层表面的积极效果，并实现了传热和冷却的增强。还进行了可视化，展示了带有生物涂层的测试表面产生的气泡和蒸汽柱的气泡动力学。使用嗜热栖热菌P2涂层表面在沸腾传热和冷却方面达到了卓越的性能。因此，本研究清楚地证明了带有生物涂层的未来表面在实现大幅节能和提高效率方面的潜力。
