MHD Tangent Hyperbolic Nanofluid Flow Past an Upper Horizontal Surface of a Paraboloid of Revolution: A Numerical Study

<sec> <title>Purpose:</title> The present work is to investigate non-Newtonian tangent hyperbolic in the presence of nanoparticles and chemical reaction past an upper horizontal surface of a paraboloid of revolution (UHSPR). For the numerical simulations, magnetic effect, a case of unequal diffusion co-efficients and radiation effect have been considered. </sec> <sec> <title>Technique:</title> Similarity transformation is applied to reshape nonlinear PDEs into ODEs. For the solution of the nonlinear ODEs, MATLAB built-in bvp4c package is applied. The validity of the MATLAB code is confirmed by reproducing already published results. </sec> <sec> <title>Findings:</title> Graphical results and tables are utilized to show the Notable effect of parameters including dimensionless velocity, concentration and temperature. Our research shows that a higher power law index shows the effect of slow fluid motion, while Grashof number has the opposite effect. It is also observed that if the Prandtl number is increased from the value 10 to 20, the rate of heat transfer increases by 17.3%. </sec>
