摘要
对一种紧凑式矩形阵列喷射冷却系统进行了系统设计、喷射性能模拟和实验。模拟采用Eulerian模型得出射流两相区相界面和不同壁面温差下的热流量及其在冷却表面的分布;通过模拟和实验比较,分析射流冲击冷却的特点及适用范围,并通过实验分析了冷却表面热流量与壁面温差的关系,以及该设计系统的冷却能力。
An experiment for jet impingement cooling and performance simulation was done before experiment based on jet impingement cooling system. The Eulerian mode was used in simulation to calculate the phase volume distribute and relationship between heat flux and temperature of the wall. Some test data agree with the simulation results. The heat transfer capacity and convective coefficient from simulation and experiment could be used as references in deep application about this technology.
