Comment on the homogeneous nanofluid models applied to convective heat transfer problems

摘要: In several recent papers, the heat transfer characteristics of nanofluids have been investigated by simply replacing transport coefficients base fluid effective nanofluids. The present note emphasizes, however, that governing equations these homogeneous nanofluid models (in which velocity-slip effects nanoparticles are neglected) can be reduced with aid elementary scaling transformations to respective regular fluids. Thus, corresponding results recovered from solutions already solved problems simple arithmetic operations, without any additional research effort. This feature is illustrated here specific examples classical Blasius and Sakiadis forced convection problems.
