Bioconvective triple diffusion flow of micropolar nanofluid with suction effects and convective boundary conditions

This investigation reveals the triple diffusive bioconvective applications subject to micropolar nanofluid flow caused by oscillating stretched surface. The problem is subject to applications of radiative phenomenon and viscous dissipation features. In oscillating stretching surface, the porous medium and suction/injection features are considered. The modeling of flow problem is based on system of partial differential equations (PDE's). Such system is solved with implementation of homotopy analysis method (HAM). The convergence region is specified against HAM solution. Understanding of flow problem is observed by vary various flow parameters to evaluates the fluid velocity, micro-rotational velocity, temperature field, solutal concentration, nanoparticles concentration and microorganisms profile. The results for skin friction, Nusselt number, solutal Sherwood number, nano-Sherwood number and microorganism's density number are also presented. It has been observed that variation of velocity against time periodically oscillates and magnitude of oscillation declined due to porous parameter and suction/injection constant. The temperature profile enhances due to modified Dufour number and Eckert parameter. Moreover, the solutal concentration reduces due to regular Lewis number.
