摘要：

The effect of Al2O3 particles on the heat transfer performance of an oscillating heat pipe (OHP) was investigated experimentally. Water was used as the base fluid for the OHP. Four size particles with average diameters of 50 nm, 80 nm, 2.2 mu m, and 20 mu m were studied, respectively. Experimental results show that the Al2O3 particles added in the OHP significantly affect the heat transfer performance and it depends on the particle size. When the OHP was charged with water and 80 nm Al2O3 particles, the OHP can achieve the best heat transfer performance among four particles investigated herein. In addition, it is found that all particles added in the OHP can improve the startup performance of the OHP even with 20 mu m Al2O3 particles. (C) 2011 Elsevier Inc. All rights reserved.
