Influence of Sonication on the Stability and Thermal Properties of Al₂O₃ Nanofluids

Figure 8

Several sets of data on the thermal diffusivity of Al₂O₃ nanofluids as a function of NPs concentrations ((a)-(b)) using different sonication techniques for two different NPs sizes types, (a) A and (b) B, and ((c)-(d)) for two NPs sizes, (c) bath sonicator and (d) probe sonicator.
