A combined experimental and theoretical investigation is conducted to study the phenomenon of mist cooling of a heated surface. In the experimental investigation, extensive use will be made of the recently developed two-phase suspension flow laser-Doppler particle-sizing anemometry techniques at Stony Brook to measure the dynamics of the two coupled phases in the mist which leads to droplet deposition. In the theoretical investigation, new aproaches will be developed towards an understanding of the droplet deposition phenomenon based on a new theory of the dynamic response characteristics of a particle in a turbulent flow.

对受热表面的雾化冷却现象进行了理论和实验相结合的研究。在实验研究中，将广泛使用最近在Stony Brook开发的两相悬浮流激光-多普勒颗粒测速技术来测量导致液滴沉积的雾中两个耦合相的动力学。在理论研究中，基于颗粒在湍流中的动态响应特性的新理论，将发展新的方法来理解液滴沉积现象。
