Simulation of Fe3O4-H2O nanoliquid in a triangular enclosure subjected to Cattaneo–Christov theory of heat conduction

Purpose The purpose of this research is to describe the importance of the Cattaneo–Christov theory of heat conduction in a triangular enclosure with a semi-circular heater. Analysis subjected to Fe3O4-H2O nanofluid is reported. Viscosity dependent on magnetic field is taken into consideration to simulate ferrofluid viscosity. Besides, heat generation and shape factor of nanoparticles are also considered. Design/methodology/approach The well-known control volume finite element method is used for simulations. Findings The outcomes reveal that the magnetic field can be introduced to the system as a controlling element. Originality/value No such analysis exists in the literature.
