Thermal enhancement and bioconvective analysis due to chemical reactive flow viscoelastic nanomaterial with modified heat theories: Bio-fuels cell applications

Owing to high thermal predictions, the scientists have utilized multidisciplinary contributions of nanofluids in various engineering and scientific problems. Based on exclusive heat transfer results, the contributions of nanomaterials are commonly addressed in thermal devices, chemical reactions, vehicle engines, fusion processes, energy outcomes and many industrial systems. Recently, it is emphasized that the suspension of nanoparticles with microorganisms show valuable applications in the fertilizers, petroleum sciences and bio-fuels. Based on such novel applications, in current research work, a mathematical model is developed for viscoelastic nanofluid under the suspension of microorganisms. The analysis is further updated with applications of magnetic force, chemical reaction and radiative influence. Unlike to tradition research approach, here the modified expression of thermal heat flux via Cattaneo–Christov (CC) relations are adopted for modeling the problem. Furthermore, the nature of thermal conductivity is considered to be variable. The oscillating surface with stretching velocity is assumed to be source of flow. The whole problem is expressed in terms of complicated and nonlinear PDE's for which analytic process is adopted. Onset of parameters are addressed physically and various applications are suggested. It is noticed that presence suction/injection parameter and permeability of porous space enhanced the heat transfer rate. The concentration phenomenon declined with viscoelastic parameter.
