Mathematical Investigations Into Boundary Layer Flows Of Casson Nanofluids With Heat And Mass Transfer Characteristics

Abstract

Mounting Temperatures In Electronic Devices During Operation May Damage Sensitive Internal Com Ponents If Too Much Thermal Energy Is Accumulated Inside The System. The Advent Of Innovativeultrahigh-Performance Thermal Management Technologies Known As Nanofluid Has Provided A Ver Itable Platform To Improve System Performance And Reliability By Removing The High Heat Gener Ated In Engineering And Industrial Devices. Hence, Due To Its Numerous Significance, The Studyof Boundary Layer Casson Nanofluid Flow With Mass And Heat Transfer Has Garnered Vast Interestin Engineering Applications. Therefore, This Dissertation Examined The Combined Applications Ofboundary Layer Casson Nanofluid Flow Through A Non-Darcian Porous Medium In The Process Ofmass And Heat Transfer Enhancement. Taking This Into Consideration, Theoretically Computationalanalysis Has Been Done On Casson Fluid Flow Problems Such As Thermophoresis And Brownian Mo Tion Effects On Boundary Layer Casson Nanofluid Flow With Mass And Heat Transfer Subjected To In Jection/Suction And Chemical Reactions, Modeling Of Heat Enhancement Characteristics Of Cu-H2o Casson Nanofluid Flow Subjected To Injection/Suction, And Stagnation Point Flow Of Cofe2o4/Tio2-H2o-Casson Nanofluid Past A Convectively Heated Permeable Slippery Shrinking/Stretching Sheetin A Darcy-Forchheimer Porous Medium In The Presence Of Viscous Dissipation. By Applying Suit Able Similarity Transformations, The Governing Nonlinear Partial Differential Equations (Pdes) Areconverted Into A System Of Nonlinear Ordinary Differential Equations (Odes) And Then Tackled Nu Merically Using The Shooting Method With The Runge-Kutta-Fehlberg Fourth-Fifth Order (Rkf45)Integration Procedure Embedded In The Maple Software Package. In All Problems, Dual Solu Tions Are Demonstrated, And Using Hydrodynamic Temporal Stability Analysis, Their Properties Areinvestigated. The Impacts Of The Embedded Governing Parameters On Temperature, Velocity, Andconcentration Profiles, As Well As Skin Friction Coefficient, The Nusselt And Sherwood Numbers Aredemonstrated In Detail Through Graphs, Charts, And Tables. The Stability Analysis Revealed That Onlythe Upper Branch Solutions Are Stable And Physically Realizable, Whereas The Lower Branch (Second)Solutions Are Unstable And Physically Unachievable. Furthermore, The Smallest Positive Eigenvalueis Numerically Displayed For The Upper Branch Solutions
