| Abstract: | A numerical study was performed in this article to discuss torsional flow of nanofluid moving between two concentric cylinders in the presence of magnetic field. The copper nanoparticles (Cu) were evenly distributed in water ( H 2 O ), which was selected as the conventional base fluid. The system of flow governing equations was reduced into dimensionless form by utilizing dimensionless quantities. The obtained dimensionless system was solved with the help of "Bvp4c" technique and validated with shooting technique using RK4 method. The findings of several essential parameters on flow profiles were illustrated graphically with detailed explanations. It was discovered that when both cylinders rotates in the same direction, the fluid velocity improves due to the outer rotational velocity 0.3 ≤ Ω 2 ≤ 0.9 . In addition, the aspect ratio of radius 0.3 ≤ Υ ≤ 0.9 , which is a characteristic of concentric cylinders, reduces the flow velocity when the cylinders rotates in the same direction. This study can be applied to many spinning components, such as turbojet cooling systems, chemical mixing equipment and electric motors. Consequently, improving heat transfer in these equipments is highly significant. [ABSTRACT FROM AUTHOR] |
