Shape factor analysis of a magnetohydrodynamics mixed convective Nimonic 80A/water nanofluid flow over a moving wedge in the presence of thermal radiation

One of the most common problems faced in the industries is the lack of proper heat energy and temperature distribution management systems. The study of the effects of thermal radiation and magnetohydrodynamics on a water-based nanofluid flow with various shapes of the nanoparticle Nimonic 80A, over a moving wedge, is yet to be studied by any researcher. Being a superalloy of nickel–iron–chromium, Nimonic 80A is often used in exhaust systems and chemical plants as an anti-corrosive agent. The mathematical model presented in this article was transformed using similarity transformations and solved using MATLAB bvp4c code. All the results and graphs were formulated after a positive outcome of our results with that available in the existing literature. Increases in velocity and temperature were observed with the increase in empirical shape factors of the nanoparticle for various parameters. Local Nusselt number and skin-friction coefficients decreased under the influence of augmenting shape factors of the nanoparticles. The velocity profile decreased at a rate of 1.5% while the temperature profile augmented by 0.24% for an augmenting magnetic parameter from M = 0.6 to 0.8 while the velocity profile increased for an increase in radiation parameter. An increment in the nanoparticle concentration resulted in incrementing streamline values and skin friction coefficient by 0.38% and 6.83%, respectively.
