Thermally Stratified Bodewadt Flow of Hybrid Nanofluid

Abstract

Present thesis represents the in-depth research of thermally stratified Bӧdewadt flow of hybrid nanofluid (HNF) containing different shaped hybrid nanoparticles (NPs) past a stretching stationary disk surface including generalized slip condition along with the consequences of thermal stratification and heat source impacts. Behavior of hybrid thermophysical features of CuO, Cu and Ag nanoparticles are analyzed past a stretching stationary disk frame. Two different shaped nanoparticles, namely CuO and Cu in spherical configuration and Ag in cylindrical shape are investigated in this analysis. Two different shaped hybrid models are taken into account in this research which are CuO− Ag −water HNF and Cu − Ag −water HNF. Uniqueness of this research work is supplemented by using the consequences of thermal stratification and heat source on thermally stratified Bӧdewadt flow of hybrid nanofluid. In this research work, the formulation is hybrid nanofluid (HNF) flow containing CuO, Cu and Ag NPs with BF water ( ) 2 H O over a stretching stationary disk frame. Well suited transformations are employed to obtain dimensionless governing equations. Numerical solutions are achieved via shooting method with coexistence of Runge–Kutta (RK) method. Graphical illustrations are used to display the impacts of physical emergent variables on velocity, temperature, and concentration profiles. It is observed that the degradation of boundary layer (BL) thickness is significantly influenced by the uniform stretching of the disk. Prandtl number and stretching parameter are the physical parameters used in this research. Especially the typical Bodewadt BL is significantly changed by the stretching of the wall in the radial direction of the stationary disk. The thickness of the TBL is also observed to significantly drop even for moderate stretching strength as an outcome of the depletion in the momentum BL. This result is noteworthy from a technological standpoint since, in real-world applications, the radial stretching might help to cool down the system. However, this research analysis is useful for the progress point of view of a cooling system in an industrial sector, micro-manufacturing, for the treatment of cancer patients and in voltaic devices, hybrid-powered engines and solar energy applications in the real world
