【 摘 要 】

Owing to the multidisciplinary significance and dynamic applications of nanoparticles, the research in areas of thermal and process engineering has been expanding every day. The nanomaterials with extraordinary thermal and physical properties are being studied to pose some astonishing contributions in various fields. The nanomaterials when taken with microorganisms in a solution for collective transport, referred as mix fluids, greatly improve the thermal efficiency during heat transfer phenomena. Usually, the mixed fluids particles have greater advantage of being controlled by some physical stimuli of light, gravity and density along with electrical and magnetic forces. The current study offers some innovative applications of induced magnetic field for the bio-convection pattern third grade nanofluid under the influence of extraordinary activation energy and non-uniform hear source/sink factors. The assumptions of stagnation points are considered under the influence of stretched. The nano-materials have been mixed with microorganism to prepare a mixed fluid in order to obtain more stability and directed transportation. The flow constraints for the thermal transport phenomenon have been explained by using convective boundary approach. The couple and nonlinear equations have been put forward to present the model and the solution has been derived using shooting algorithm technique. Moreover, the numerical and graphical outcomes from the study are presented using tables and figures. The improved profile of velocity is predicted against higher values of velocity ratio, Reynolds number and third grade fluid parameter. The induced magnetic field profile enhanced for reciprocal magnetic Prandtl number and magnetic parameter. The consideration of non-uniform heat source/sink is more effective to improve and control and thermal transportation process.
