Wave oscillations in thermal boundary layer of Darcy-Forchheimer nanofluid flow along buoyancy-driven porous plate under solar radiation region
Abstract
The significant contribution of current mechanism is to explore the periodical and fluctuating results of heat and mass flux of Darcy-Forchheimer nanofluid flow along buoyancy-driven porous plate under solar radiation region. Flow through a Darcy-medium has a wide range of applications such as the use of oil in various hydrothermal transfer control, radioactive nuclear disposal systems, water improvement, and filtration of water. The dimensional model is transformed into non-dimension for scaling factors. The primitive-based transformation is applied on steady and oscillatory parts for smooth algorithm in FORTRAN language machine. The convenient model is again reduced into algebraic pattern by using implicit finite difference method. The numerical and graphical results of velocity, temperature and concentration are executed by Gaussian elimination method. To enhance the frequency and wavelength, the impact of solar radiations, thermophoresis, Brownian movement, Schmidt factor, Prandtl factor, porosity and buoyancy pressure is applied on periodic nanoparticles with Darcy Forchheimer relation. The novelty of this proposal to explore the wave oscillations, amplitude and phase angle of thermal and concentration boundary layer of Darcy-Forchheimer nanofluid flow along buoyancy-driven porous plate under solar radiation region. It is noticed that the prominent wavelength and frequency in thermal and concentration boundary layers is generated under porous and solar radiation region. The significance of temperature variation increases as solar radiation, Brownian motion and thermophoresis increases. It is noticed that heat and mass transport enhances as Darcy-Forchheimer and modified buoyancy force increases. In thermodynamic systems, the Darcy-porous materials is prominent assumption that is employed in many domains, especially clinical science, petrochemical and structural engineering, geography, biochemistry and biological physics, and material science. For energy storage and energy conservation, the Darcy-porous material is required for batteries, fuel cells and super capacitors.
