Generalized Hybrid Nanofluid Model with the Application of Fully Developed Mixed Convection Flow in a Vertical Microchannel

The fully developed mixed convection hybrid nanofluid flow in a vertical microchannel is examined in detail.The simplified hybrid model that omits the nonlinear terms due to the interaction of different nanoparticle volumetric fractions is derived and compared with the existing one.The generalized model describing hybrid nanofluid suspended with multiple kinds of solid particles is suggested.The argument that the corresponding nanofluid solutions obtained by the homogenous model can be recovered from the results of the regular problems through simple arithmetic operations is checked.Solutions in similarity form for this flow problem are formulated by means of a set of similarity variables.The effects of various parameters on important physical quantities are analyzed and discussed.
