【 摘 要 】

The purpose of this work is using distilled water as working fluid to study the spray cooling heat transfer characteristics from non-boiling zone to boiling zone by CFD method. Simulation is performed using a Euler-Lagrangian method based on the air and liquid droplet two phase flow dynamics. The results of this simulation are in accordance with the experimental results of the laboratory. The simulation results show that the spray height is an important factor influencing the cooling characteristics. With the decrease of spray height, the heat transfer effect is enhanced.
