Parametric simulation of micropolar fluid with thermal radiation across a porous stretching surface

Abstract

The energy transmission through micropolar fluid have a broad range implementation in the field of electronics, textiles, spacecraft, power generation and nuclear power plants. Thermal radiation's influence on an incompressible thermo-convective flow of micropolar fluid across a permeable extensible sheet with energy and mass transition is reported in the present study. The governing equations consist of Navier–Stokes equation, micro rotation, temperature and concentration equations have been modeled in the form of the system of Partial Differential Equations. The system of basic equations is reduced into a nonlinear system of coupled ODE's by using a similarity framework. The numerical solution of the problem has been obtained via PCM (Parametric Continuation Method). The findings are compared to a MATLAB built-in package called bvp4c to ensure that the scheme is valid. It has been perceived that both the results are in best agreement with each other. The effects of associated parameters on the dimensionless velocity, micro-rotation, energy and mass profiles are discussed and depicted graphically. It has been detected that the permeability parameter gives rise in micro-rotation profile.

Non-Fourier energy transmission in power-law hybrid nanofluid flow over a moving sheet

“…There are some notorious classes of NNF, whose shear rate is not independent of flow direction. Shear rate-dependent viscosity fluids are subdivided further Herschel–Bulkley, Casson fluids, Bingham fluids, Carreau-Yasuda fluid, Carreau fluids and power-law fluid 1 – 6 . Minakov et al 7 described the findings of a practical assessment of the nanofluids (NF) flow incorporating nano particulates of various metals and oxides.…”

Numerical study of Williamson hybrid nanofluid flow with thermal characteristics past over an extending surface

“…The liquid flow over an extending surface under the magnetic consequences has gotten a lot of interest due to its numerous uses in engineering operations including glass fiber, plasma studies, and geothermal power production. [1][2][3] Sarada et al 4 evaluated micropolar flow in a permeable media subjected to an angled magnetic field, mass transpiration, and internal radiation over a porous stretching and shrinking surface. For the very first time, utilizing similarity substitutions, the numerical results of the temperature fields and flow were obtained in closed forms.…”

Numerical Analysis of an Unsteady, Electroviscous, Ternary Hybrid Nanofluid Flow with Chemical Reaction and Activation Energy across Parallel Plates

“…Shah et al [33] provide a concise overview of most of TiO 2 s notable properties, as well as a summary of innovative thermal applications, including its high refractive index, overwhelmingly high boiling and melting points, high stiffness and hardness, ability to absorb or reflect ultraviolet radiation, and photocatalytic nature. Recently, many researchers reported significant contributions to ternary hybrid nanofluid flow [34][35][36][37].…”
