Abstract

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.
