Hydromagnetic Flow of Casson Fluid Carrying CNT and Graphene Nanoparticles in Armory Production

Abstract

Carbon nanotubes (CNTs) and graphenes possess the properties that make them the future of armory in the military. Bullet-proof vests, for instance, are indispensable components of any military arsenal whose maintenance cost and weight can be drastically reduced if the materials are changed to CNT and graphenes. The purpose of this study is to investigate heat and mass transport phenomena in the hydromagnetic flow of Casson fluid suspending carbon nanotubes and graphene nanoparticles in armory production. An appropriate model is developed, taking into account the Buongiorno model and the effect of heat radiation. Using similarity variables, the model is reformulated into a dimensionless form. The numerical solution to the dimensionless model is obtained using the three-stage Lobatto IIIa finite difference approach, which is programmed into the MATLAB bvp4c package. The study reveals that an increase in the Casson fluid parameter leads to a decrease in the velocity profiles. There is a 78.41% reduction in skin friction when results are compared with the CNT-water nanofluid.
