“…They concluded that an augmentation in the value of “ Ln” will decline the heat transport rate, while increase mass, nano, and regular rates of transportation. Finally, Usman et al [ 28 ] examined the power-law non-Newtonian nanoliquid through a spinning disk occupied with gyrotactic micro-organisms. They used the shooting procedure to discuss the numerical outcomes and the effects of various physical parameters on the flow and heat transfer.…”

Solar thermal collectors distribute, capture, and transform the solar energy into a solar thermal concentration device. The present paper provides a mathematical model for analyzing the flow characteristics and transport of heat to solar collectors (SCs) from non-Newtonian nanofluids. The non-Newtonian power-law scheme is considered for the nanofluid through partial slip constraints at the boundary of a porous flat surface. The nanofluid is assumed to differ in viscosity and thermal conductivity linearly with temperature changes and the magnetic field is appliqued to the stream in the transverse direction. The method of similarity conversion is used to convert the governing structure of partial differential formulas into the system of ordinary differential ones. Using the Keller box procedure, the outcoming ordinary differential formulas along with partial slip constraints are numerically resolved. A discussion on the flowing and heat transport characteristics of nanofluid influenced by power law index, Joule heating parameter, MHD parameter and slip parameters are included from a physical point of view. Comparison of temperature profiles showed a marked temperature increase in the boundary layer due to Joule heating. The thickness of the motion boundary-layer is minimized and the transport of heat through boundary-layer is improved with the partial slip velocity and magnetic parameters rising. Finally, With an increase in the Eckert number, the distribution of temperature within boundary layer is increased.

Variable properties like thermal conductivity and variable thickness of the disk are analyzed for the Jeffery nanofluid and gyrotactic microorganisms in rotating system taking into account the Cattaneo‐Christov heat flux, velocity slip and thermal radiation effects. Zero mass flux is assumed at the disk surface for the better and high accuracy of the out‐turn. The governing equations of the problem are transformed into nonlinear ordinary differential equations by introducing the appropriate similarity transformations which are solved analytically by the homotopy analysis method. The effects of all the parameters are given in detail through the graphs.

The usage of nanoparticles is effectively increased in industries because of their high thermal performance. Moreover, the bioconvection phenomenon in nanomaterials leads to innovative biotechnology applications, such as biofuels, biosensors, the petroleum industry, etc. Because of the nanoparticle's exceptional performance and bioconvection phenomenon, the magnetohydrodynamics bioconvection Reiner–Rivlin nanofluid flow is considered over the rotatory stretchable disk contains the motile gyrotactic microorganisms. The heat and mass transport phenomenon with thermal radiation and activation energy is also investigated under convective‐Nield's boundary conditions. The governing partial differential equations (PDEs) are transmuted with specific similarity transformation into ordinary differential equations (ODEs). The obtained ODEs are solved numerically through the assistance of the Chebyshev spectral collocation method. The effects of the flow parameters on the boundary layer profiles are reported graphically. The graphical illustration elucidates that the dimensionless parameters have significantly affected the nondimensional boundary layer profiles. The fluid velocity, temperature, concentration of nanoparticles, and motile density of microorganisms are effectively controlled through the proper alteration of the pertinent parameters. The thermophoresis parameter decreases the heat and mass transport rates, whereas the Brownian motion parameter helps to increase them. Finally, the current research can successfully fill a gap in the existing literature.
