Abstract In order to investigate the effect of nanobubbles (NB) on the apparent viscosity of organic liquids, inorganic ceramic membranes were used to generate NB in solutions to monitor the apparent viscosity variations of liquids. CFD was used to simulate the variations of apparent viscosity of solutions with NB verify the experimental results. The experimental results show that the particle size distribution of NB is in the range of 125—425 nm at 0.3 MPa and average surface tension of H₂O decreases from 72.0 to 68.1 mN·m^-1 in the presence of NB at the liquid surface. In addition, after bubbling time of 30 min the apparent viscosity of H₂O, BSA solution and SA solution decrease from 1.07, 1.3 and 2.27 to 1.01, 1.24 and 2.27 mPa·s, respectively. The apparent viscosity of the solutions continues to decrease with increasing NB concentration. The simulations by the CFD-PBM coupled model show that the variations of the apparent viscosity of solutions are consistent with the experimental results, confirming the effectiveness of NB in reducing the apparent viscosity of liquids.
