Abstract

The ongoing research centres on the flow of tangent hyperbolic nanofluid over a Riga surface, affected by heat dissipation and radiative thermal effects. In the present study, the influence of nanofluid arises from the joint effects of Brownian motion and thermophoresis, driven by cross-diffusion phenomena and thermal radiation. As a novel approach, the bioconvection-induced motile microorganism, combined with higher-order chemical reactions, enriches the flow characteristics. The mathematical model obtained with the aforesaid assumptions is formulated and transmuted into dimensionless form by utilizing standard transformation rules. Moreover, the formulated problem is addressed numerically by utilizing the fourth-order Runge-Kutta approach via MATLAB’s embedded bvp4c solver. The distinctive response of diverse variables governing the flow dynamics is depicted through graphical representations, subsequent to corroborating the findings with prior studies.
