Abstract
In this analysis, the modified nanofluid flow at a nonlinear stretching Riga plate is considered. The impacts of variable viscosity are considered. The modified nanofluid is the extended version of the hybrid nanofluid. This is the mixture of three nanoparticle and base fluid. The heat transfer rate depends on the thermal conductivity because heat transfer rate and thermal conductivity directly proportion which provided in the literature. The developed model solved through numerical technique. The basic achievement of this analysis is to explore about the heat transfer improvement that gains higher as compared to Hybrid nanofluid and nanofluid, (see Fig. 1). Heat transfer properties and modified nanofluid show exciting behavior which deserve further study on the modified nanofluid. The phi(3) disperse the energy in the shape of heat than the mixture of more nanoparticles may more exert energy in the form of heat. (C) 2021 THE AUTHORS.
