Computation of melting dissipative magnetohydrodynamic nanofluid bioconvection with second order slip and variable thermophysical properties

摘要: This paper studies the combined effects of viscous dissipation, first and second order slip and variable transport properties on phase-change hydromagnetic bio-nanofluid convection flow from a stretching sheet. Nanoscale materials possess a much larger surface to volume ratio than bulk materials which significantly modifies their thermodynamic thermal lowers substantially melting point. Gyrotactic non-magnetic micro-organisms are present in the nanofluid. The assumed be dependent concentration and temperature. Via appropriate similarity variables, governing equation with boundary conditions converted nonlinear ordinary differential equations solved using the BVP4C subroutine symbolic software Matlab. non-dimensional boundary value features a (phase change) parameter, temperature-dependent conductive as well as slip parameters, mass diffusivity Schmidt number, microorganism diffusivity bioconvection magnetic body force Brownian motion thermophoresis parameter. Extensive computations visualized for influence of these parameters. simulation is relevance fabrication bio-nanomaterials for bio-inspired fuel cells.
