Abstract

In this work, a complex nature structure is presented to deal with the flow and heat transfer characteristics of Cu–H2O nanofluid within the irregular triangular enclosure. Influences of the various shape of Cu nanoparticles are also considered to deal with this mechanism. The irregular side (sinusoidal) of the triangular cavity is partially heated from the bottom. A fixed magnetic field is horizontally applied to the enclosure. The governing equations are derived in the form of nonlinear coupled partial differential equations comprising energy, momentum, and continuity equations. These equations are firstly nondimensionalized before being numerically simulated via Control Volume based Finite Element Method (CVFEM). The relation among the diverse parameters is defined in the form of correlation for Nusselt number. The study concludes that the heat transfer rate is ascended owing to the ascendant in Rayleigh number and descended owing to the ascendant in Hartmann number. Particle shape factor also plays a crucial role in the heat transfer rate within and at the surface of the enclosure.
