“…Thermal and solutal convection with chemical reaction has numerous applications in manufacturing processes, for example, in evaporation on the surface of a water body, distribution of temperature, energy distribution in a wet cooling tower, drying, due to freezing the crops are damaged and also in geophysics and volcanic systems [18,19]. Ferdows and Qasem [20] investigated the influence of chemical reaction on linearly stretching sheet in a viscous fluid.…”

The effect of unsteady MHD flow of a micropolar fluid over an inclined plate with thermal radiation and non-uniform heat source/sink, non-linear thermal radiation, chemical reaction and convective boundary conditions has been investigated in the present study. A mathematical model is developed to set of Partial differential equations into non-linear coupled ordinary differential equations and then solved numerically by spectral relaxation method (SRM) with finite difference scheme which employs the Gauss-Seidel type of relaxation approach to linearize and decouple the system of differential equations and then Chebyshev pseudospectral method was used to solve the equations. The influence of various physical parameters are depicted graphically and analyzed in details. An excellent agreement of accuracy has found after comparing present work with previously published work.

The transient MHD stream of a Fe3O4 water based nano flow fluid past moving vertical holey semi-infinite holey surface and convective in the company of chemical reaction, thermophoresis and consistent heat basis in a turning casing of orientation is examined. The platter is considered to waver in moment with steady recurrence. The impacts of parameters entering into the problem inside the periphery layer for the stream, temperature and concentration are analyzed for magnetite water based nanofluid through diagrams.

Effect of magnetic field orientation on free convection of several water-based nanofluids in a square porous cavity is analyzed in this study. To this aim, the heatline visualization technique is implemented for the first time. Moreover, streamlines and isotherms are employed to present fluid flow and temperature distribution. The governing equations are transformed into a dimensionless form and then solved using the finite-volume method. Computations are undertaken for different orientations and magnitudes of the imposed magnetic field in circumstances with distinct Rayleigh numbers and the nanoparticles types and volume fractions. The corresponding results are presented in terms of dimensionless distributions of streamlines, isotherms, and heatlines as well as numerical values of the flow strength and the average Nusselt number. Inspection of the results demonstrates that increase in the magnetic field strength deteriorates the heat transfer rate. This effect, however, diminishes with rise in the magnetic field inclination angle.
