Modelling unsteady mixed convection of a nanofluid suspended with multiple kinds of nanoparticles between two rotating disks by generalized hybrid model.

The unsteady mixed convection of a hybrid nanofluid due to rotating disks is examined. The generialzied homogenous flow model that describes hybrid nanofluids containing multiple kinds of nanoparticles is developed for modelling the problem. Its simplified form is proposed based on the linear assumptions and verified by existing model. The argument that the corresponding nanofluid results by the homogenous model can be restored from those solutions of already solved regular problems via simple arithmetic operations is checked. The relation of similarity variables to nanoparticles volumetric fractions is discussed. [ABSTRACT FROM AUTHOR]
