A modified prediction model for viscosity of nanofluids based on molecular dynamics simulation

Classical viscosity predicting models for conventional-scale particle suspensions failed to predict viscosities of nanofluids. Based on molecular dynamics simulation, the present work deliberated on the effects of absorption layer and nanoparticle agglomeration, and presented a modified predicting model for viscosity of nanofluids. The predicting values of the modified model for viscosities of nanofluids were well in agreement with experimental results. The diameter of nanoparticle agglomeration and thickness of absorption layer were found to be important influencing factors for viscosities of nanofluids that should be considered.
