Statistical and computational analysis on bioconvective MHD Oldroyd-B fluid over a flat surface

Abstract

This study aims to discover the application of bioconvection and heat absorption or omission aspect of 2D incompressible MHD Oldroyd-B nanofluid over the stagnation region. Directed by suitable similarity transformations, the system of PDEs is transformed into a system of coupled nonlinear ODEs. The results were made by using Runge–Kutta shooting technique. The Buongiorno model is capitalized while Oldroyd-B model is employed for portraying the viscoelastic behavior of the flow. In order to visualize the impact of relevant parameters on momentum boundary layer, temperature, concentration and microorganism profiles are computed graphically. Numerical outcomes for the local Nusselt number, Sherwood number, microorganism number and local skin friction number are calculated for different parametric situations to provide interesting features of the examination. Furthermore, it has been also observed from statistical point that the correlation coefficient of the local Nusselt number, Sherwood number, microorganism number and local skin friction number with various parametric situations are highly significant at the [Formula: see text] level of significance ([Formula: see text] for a two-tailed test).
