| Summary: | Nanofluid is a modern class of heat transfer fluids made of a base fluid containing nanometer-sized particles. Heat and mass transfer in boundary layer flow of non-Newtonian nanofluid over a stretching surface is of significant concern in various engineering applications. Hence, this thesis studied the heat and mass transfer of non-Newtonian micropolar and Casson nanofluids flow over an inclined stretching surface. The considered problems involved linear, nonlinear, and permeable inclined surfaces. Similarity transformations are employed to transform the nonlinear partial
differential equations into nonlinear ordinary differential equations. The numerical solutions are obtained by using Keller-box method. The physical quantities such as skin friction, Sherwood number, Nusselt number, velocity, temperature, and concentration profiles with different effects of material parameters are examined. This
study found that in micropolar nanofluid flow problems, the material parameters enhanced Nusselt number, Sherwood number and skin friction. Further, velocity profile increases with increase in material parameter. Similar behavior also observed in the case of angular velocity profile against material parameter. Meanwhile, Nusselt number and Sherwood number decrease whereas skin friction increases with increasing surface inclination and magnetic parameter. Nanofluid velocity decreases whereas temperature and concentration increase with increasing Casson parameter. Velocity
profile is found to increase by increasing local Grashof number and modified local Grashof number. The present results are validated and in good agreement with published results in literature. |
