The present study is concerned with the bioconvective magneto-nanofluid flow of copper–water containing gyrotactic motile microorganisms across a vertically spinning cone in a porous regime. Bioconvection in nanofluid is important in bioscience, such as for delivering drugs, content detection, micro-enzymes, biological sensors, and nanotechnology, among other applications. The aim of the current study is to observe flow characteristics following the addition of Cu nanoparticles including the contribution of variable heat source, Joule heating, and Arrhenius energy activation. The research methodology used to construct the article is as follows: The first section is "Introduction," which contains some literature review. The governing equations for the proposed study were developed in the "Mathematical Formulation" section. The leading partial differential equations (PDEs) are converted to nonlinear ordinary differential equations (ODEs) by applying the proper similarity variables. These equations are then solved by the MATLAB bvp4c tool. The third section contains results and discussion. This section examines the behavior of numerous physical factors for density motile microorganisms (DMM), velocity, concentration, temperature, density number of microorganisms, tangential and azimuthal skin frictions, mass transport rate, and heat transport rate are studied graphically. Results show that activation energy enhances the thickness of the temperature and concentration boundary layer while it reduces the mass transport rate. Eckert number raises tangential velocity while reducing the normal velocity. The volume fraction parameter raises the thermal boundary layer. Moreover, the rate of heat transport reduces for thermophoresis number and buoyancy ratio parameter. The fourth section is "Comparison and Validation," which contains a comparison of current work, which is intended to constitute a good agreement. The fifth section, "Conclusion," contains some major conclusions of this study. [ABSTRACT FROM AUTHOR] |
