摘要
This investigation reveals effect of induced magnetic field on stagnation point flow over a stretching sheet containing gyrotactic microorganisms. The nonlinear system of coupled differential equations is transformed and solved numerically with the help of shooting method along with Runge-Kutta method of order 5. The solution accuracy is set up to 6 decimal places. Main focus is to examine influence of induced magnetic field and thermal radiation on fluid flow and microorganism density. The behavior of fluid velocity, temperature, concentration and microorganism density for distinct values of pertinent physical parameters is examined. The results are displayed through graphs and tables. Main findings of present analysis are abridged in concluding remarks. It is concluded that bioconvection plays a vital role in reducing temperature and concentration profiles. Moreover, microorganism density rises with the rise in Peclet number P-e,magnetic parameter epsilon,Brownian motion parameter N-b and thermophoresis parameter N-t while it reduces for rise in Lewis number. Present results are validated by comparative analysis and they are found to be in good agreement. (C) 2016 Elsevier B.V. All rights reserved.
