Modified Cattaneo-Christov analysis for radiated micropolar nanofluid flow with bioconvection phenomenon and nano-biofuel applications

Purpose The suspension of microorganisms in nanomaterials presents excellent thermal stability and impressive properties. The current analysis aims to investigate the significance of bioconvection associated with the time-dependent flow of a micropolar nanofluid governed by an oscillatory sheet. Design/methodology/approach The consequences of the porous medium and magnetohydrodynamics are examined. The heat transfer modeling is updated by using the Cattaneo-Christov hypothesis. The flow is further driven by external thermal sources and radiative impact. Under the assumed theoretical assumptions, the flow model is developed, further simplified into dimensionless equations. For computational simulations, the homotopy analysis scheme is implemented. After ensuring the convergence region, a graphical analysis is performed. The problem is further visualized in a 3D pattern. The proposed results may find significant applications in nano-biofuels and heat management systems. Findings After ensuring the convergence region, a graphical analysis is performed. The problem is further visualized in a 3D pattern. The proposed results may find significant applications in nano-biofuels and heat management systems. Originality/value The model is based on the amplification of the revised flux theories, namely, the Cattaneo-Christov model. Insight into the radiated phenomenon and the external thermal (heat) source is observed. The solution of the governing equations was treated with the homotopy analysis method. A physical analysis and 3D illustration of the problem are presented.
