Insight into influence of thermal radiation and Cattaneo–Christov model on ternary hybrid nanofluid (TiO2–Al2O3–MoS2/kerosene oil) and hybrid nanofluid (TiO2–Al2O3/kerosene oil) flow and heat transfer over a stretching sheet

Abstract

The present research reports the impact of the Cattaneo–Christov (C-C) model and thermal radiation in concert with the suction/injection on boundary conditions on TiO2–Al2O3–MoS2/Kerosene oil ternary hybrid nanofluid (THNF) over a stretching sheet. The authors have also done a comparative analysis of the heat and mass transfer rate of ternary hybrid nanofluid and TiO2–Al2O3/Kerosene oil hybrid nanofluid flow. The code validation is done with a published study as a special case to validate the numerical code used to derive the numerical results of the present flow model. The flow equations are altered into ODEs with the help of similarity transformation, which are solved in MATLAB by the “bvp4c technique.” The graphs are drawn w.r.t. various parameters: heat source/sink, radiation, chemical reaction, suction/injection, thermal relaxation, and magnetic parameter. The influence of the aforementioned parameters on the velocity profile, thermal profile, concentration profile, heat, and mass transfer profile is displayed by graphs and tabular values. The heat and mass transfer rate enhance by elevating the value of the heat source/sink and radiation parameter. On boosting the magnitude of injection at the surface, the rate of mass transfer elevates. The results of this study can be used in various applications including drainage issues, chemical engineering, solar panels, solar absorption and filtration, ground stream hydrology, solar cells, and others, where flow over a sheet illustrates its significance and applicability.
