;8 mm × 3 mm were cut from the heat treated ingot, and polished to a 2000-grit SiC paper, then degreased in acetone, ultrasonically cleaned in alcohol, and finally dried in air. Table 1......
mesh. SiC/water was employed as working fluid with various mass concentrations. By using nanofluid, thermal resistance decreased. Reductions in thermal resistances were 11%, 21% and 30% for 0.35%, 0.7.... Their obtained thermal resistances under various working conditions are shown in Figure 4. HOSEINZADEH et al [156] utilized Al2O3/water and SiC/water nanofluids in a thermosyphon. It was observed......
