Abstract

Abstract: This article analyzes the heat transfer, non-linear thermal radiation, the Cattaneo-Christov heat flux model and velocity slip effects in hybrid nanofluid flow over a 3D moving sheet. The hybrid type nanoparticles like Ag-Cu and MoS2 and GO are suspended in working liquid. Hybrid nanoliquid is homogeneous-mixture with novel physical and chemical structures making it a promising option for improving thermal efficiency. Hybrid nanoliquids have high ability to absorb and preserve the hydrogen because of their very huge unique surface-area and distinctive and unusual nature of an each nanostructure. Nanostructure carbon atoms like graphite, graphene and few metals like molybdenum and magnesium have recently been found to store hydrogen due to their larger storage-capacity and the higher dehydrogenation and hydrogenation speeds. The system of the mathematical relation in PDEs form is converted to system of ODEs by employing suitable variables. The bvp4c tool available in computational software MATLAB is used for solving the dimensionless ordinary differential system. Furthermore, the flow expectations for each physical flow parameter like 0.1 ≤ α ≤ 1.2, 0.4 ≤ β ≤ 1.2, 2.0 ≤ P r ≤ 5.0, 0.1 ≤ γ ≤ 1.2, 0.2 ≤ R e ≤ 0.8, 0.1 ≤ M ≤ 1.2, 0.0 ≤ R d ≤ 0.8, 0.1 ≤ E c ≤ 0.4, 0.1 ≤ N r ≤ 1.2, 0.2 ≤ ϕ 1 = ϕ 2 ≤ 0.5., 0.1 ≤ Ω ≤ 0.6, 1.5 ≤ θ w ≤ 1.8, are discussed. The physical consequence of flow parameters against subjective flow fields are graphically highlighted with physical justifications. The vitality of prominent parameters against velocity field and temperature distribution is illustrated through graphs. The velocity field diminishes with a larger velocity slip parameter. The velocity field is enhanced by the higher estimations of the Grashof number. The consequence of temperature ratio parameter on thermal field is delineated. By enhancing the thermal relaxation parameter, the thermal field reduces.
