Influence of external magnetic source on ferrofluid convection in an enclosure with elliptic hot cylinder is studied. Governing formulae are first made dimensionless form along with the associated boundary conditions and then solved by powerful numerical method namely CVFEM. Influences of Rayleigh and Hartmann numbers and Fe3O4 volume fraction on hydrothermal behavior are presented. https://vintagebohobages.shop/product-category/belt/
