Nanofluid suspension comprises a chip-sized rigid particle trapped in the convection fluid. These forms of fluids are known as nanofluids. Nanofluid is more user-friendly in engineering including fuel cells, cooling systems, and a wide range of applications of technologies to improve. The idea of this work is to analyze the Bio convectional stream characteristics and Solutal boundary characteristics of nanofluid flow via a wedge. Furthermore, the consequences of motile bacteria and heat conductivity are considered. When the boundary layer is estimated, the governing equations will be seen. Coupled PDEs are reduced into nonlinear ODEs using the required similarity vector, and the resultant structures are shown using the MATLAB computational tool bvp4c firing (Labotto IIIA formula). The implications of fluid velocity, temperature area, nanoparticles concentration, and microorganism concentration on the induced parameters are shown in graphical and numerical values. The velocity field is booming up for higher fluid parameter values and depressed for larger buoyancy ratio parameter estimations. For increasing levels of both the thermal conductivity parameter and the thermal Biot number, the temperature field rises. The microorganism’s field has dropped for Peclet number values and increased for Microorganisms Biot number values. The concentration field is lowered for the Lewis number while it is increased for the concentration Biot number. The current implications are novel and original for the investigation of flow and heat transfer over a wedge in a viscoelastic nanofluid with thermal conductivity, motile microorganisms, and bioconvection.
