Heat and mass transfer in Maxwell fluid with nanoparticles past a stretching sheet in the existence of thermal radiation and chemical reaction

Abstract

ABSTRACTThe objective of this work is to examine the distinctive features of heat and mass transfer in a 2-dimensional Maxwell fluid that is incompressible and contains electrically conducting nanoparticles. They are illustrated by using a stretched sheet with convective boundary conditions and a heat source/sink in the presence of thermal radiation and chemical interaction. Studies of hydromagnetic flow and heat transfer across a stretched sheet have lately attracted a great deal of attention as a result of its numerous industrial applications and a huge impact on a broad variety of manufacturing processes. Power plants, heat exchangers, MHD generators, aerodynamics, plastic sheet extrusion, condensation processes, and metal spinning are examples of these processes. The partial differential equations (PDEs) that govern the flow and the boundary conditions that correspond with them may be non-dimensionalized by using the appropriate similarity variables. The resulting transformed ordinary differential equations (ODEs) are solved using the Runge-Kutta-Fehlberg scheme of the fourth and fifth order. By assuming a value for the boundary condition, the shooting approach transforms the boundary value problem (BVP) into an initial value problem (IVP), which is subsequently solved using the RKF45 algorithm. Graphical representations of how such embedded thermo-physical parameters significantly impact the velocity, temperature, and concentration are assessed and shown. A comparison case study is made with previously published literature, and a great correlation between the results exists. The primary results of the research are that raising estimates of the chemical reaction parameter minimises the concentration distribution while increasing the thermal radiation parameter raises the temperature. As the quantity of thermophoresis rises, the thickness of the boundary layer increases, causing the surface temperature to rise, resulting in a temperature rise.KEYWORDS: Stretching sheetnanoparticlesthermal radiationMaxwell fluid Nomenclature Bi=Biot numberc=positive constantC=Concentration of the fluid molm−3Cw=Fluid concentration at the wall molm−3C∞=Fluid Concentration at infinity molm−3Cs=Concentration susceptibilityCp=Specific heat at constant pressure J.Kg−1.KCf=Skin frictionDB=Brownian diffusionDT=Coefficient of thermophoretic diffusionDM=Mass diffusivity m2.s−1f=Dimensionless velocity stream functionhf=Heat transfer coefficientk=Thermal conductivity ω.m−1.K−1k0=Maxwell fluid relaxation timeKT=Thermal-diffusion ratio parameterKr=Chemical reaction parameterLe=Lewis NumberNb=Brownian Motion ParameterNt=Thermophoresis parameterNr=Radiation ParameterNux=local Nusselt numberPr=Prandtl numberShx=local Sherwood numberT=Temperature of fluid near the plate KTw=Fluid temperature closer to the wallKT∞=fluid Temperature at infinity KTf=The temperature of hot fluidu=Dimensionless velocity along x-axism.s−1v=Dimensionless velocity along of y- axism.s−1x,y=Cartesian coordinatesGreek letters=α=Thermal diffusivityβ=Maxwell parameterσ=Electrical conductivity Ω−1m−1ρ=Fluid density (kg/m3)ρp=Density of the particlesρf=Density of the base fluidμ=Dynamic viscosityη=Dimensionless similarity variableν=Kinematic viscosity (m2s−1)θ=Dimensionless temperature of the fluidφ=Dimensionless fluid concentrationψ=Stream functionSubscripts=w=condition at the stretching sheet∞=conditions at infinitySuperscript=′=differentiation with respect to ηDisclosure statementNo potential conflict of interest was reported by the authors.Additional informationFundingThe authors received no financial support for the research, authorship, and publication of this article.Notes on contributorsN.
