Significance of the nonlinear radiative flow of micropolar nanoparticles over porous surface with a gyrotactic microorganism, activation energy, and Nield's condition

摘要

Current continuation presents the numerical study regarding stretched flow micropolar nanofluid over moving the sheet in the existence of activation energy and microorganisms. Furthermore, nonlinear aspects of thermal radiation are also utilized in the energy equation which results in the energy equation becomes highly nonlinear. This investigation has been performed by using convective Nield boundary conditions. First, useful dimensionless variables are implemented to reduce the partial differential into ordinary ones. Later on, the approximate solution of the transformed physical problem is computed by using the shooting scheme. A detailed physical interpretation of obtained results is also presented for velocity, temperature, motile microorganisms density, and mass concentration profiles. A detailed graphical explanation for each engineering parameter has been discussed for some specified range like 0 ≤ K_1 ≤ 1.5, 0.1 ≤ m ≤ 0.7, 0.1 ≤ K ≤ 0.7, 0.1 ≤ Nt ≤ 2.4, 0.1 ≤ γ ≤ 0.4, 1.0 ≤ Pr ≤ 1.8, 0.4 ≤ Rd ≤ 1.0, 0.2 ≤ Nb ≤ 0.8, 0.1 ≤ E ≤ 7.0, and 0.4 ≤ Lb ≤ 1.0. The theoretical computations based presented here can be more proficient to attain the maximum efficiency of various thermal extrusion systems and microbial fuel cells.
