The fundamental characteristics of the heat transfer and cooling performance of the micro-solid nitrogen particle spray impinging to the heated plate was numerically investigated and experimentally measured by a new type of integrated computational-experimental technique.The used Computational Fluid Dynamics (CFD) analysis based on Euler-Lagrange model is focused on the cryogenic spray behavior of atomized micro-solid nitrogen and on the ultra-high heat flux characteristics of the micro-solid particle.Based on the numerically predicted performance, a new type of cryogenic spray cooling technique which can be available to apply the ultra-high heat power density device is developed.

采用一种新型的计算-实验一体化技术，对微固体氮粒子喷雾撞击加热板的传热和冷却特性进行了数值模拟和实验测量，采用基于欧拉-拉格朗日模型的计算流体力学（CFD）分析方法，重点研究了雾化微固体氮粒子低温喷雾特性和超低温喷雾特性。在数值模拟的基础上，提出了一种适用于超高热功率密度装置的新型低温喷雾冷却技术。
