Abstract
The data presented in this data article comprises the critical parameters of dispersion stability such as the particle effective diameter, zeta potential, sedimentation velocity and stability factor for Cu/Al(2)O(3) single particle nanofluid and hybrid nanofluid samples at various ultra-sonication times, that is, 0.5 h, 1.0 h, 2.0 h and 3.0 h. The data for effective diameter and zeta potential was generated using the particle size analyser and zeta potential analyser respectively. The measured data for effective diameter and zeta potential was processed to generate the data for sedimentation velocity and stability factor. The ultra-sonication time with maximum value of stability factor was used for sample preparation of Cu/Al(2)O(3) single particle nanofluid and hybrid nanofluid in the related research article "On trade-off for dispersion stability and thermal transport of Cu-Al(2)O(3) hybrid nanofluid for various mixing ratios" (Siddiqui et al., 2019) [1].
