Thermal radiation and chemically reactive aspects of mixed convection flow using water base nanofluids: Tiwari and Das model

The current investigation focuses on the magneto-nanofluid mixed convective boundary-layer flow of nanofluid caused by a vertical permeable plate with nonlinear thermal radiation. Furthermore, heat and mass transfer for water-base fluids influenced by heat generation/absorption and viscous dissipation have been analyzed. The convective boundary condition is also imposed on the vertical sheet. The main aim of the study is to investigate the five different types of nanoparticles, namely, silver (Ag), copper (Cu), alumina (Al2O3), copper oxide (CuO), and titanium dioxide (TiO2) in the base fluid water. Moreover, the governing partial differential equations are converted into a set of ordinary differential equations via Sparrow-Quack-Boerner local nonsimilarity method. Additionally, nonlinear ODEs are successfully tackled by the Runge-Kutta-Fehlberg method. Physical parameters are examined graphically along with the velocity, temperature, and concentration distribution. Further, the skin friction coefficient, local Nusselt number, and Sherwood numbers are also studied in detail using graphs. The results show that increasing the value of buoyancy parameter and magnetic parameter fluid exhibits more resistance in the fluid, thereby fluid velocity and momentum boundary layer reduce. Moreover, the radiation parameter transmitted more heat from the surface to the fluid; as a result, the fluid temperature is boosted.
