Abstract This study is numerically executed to investigate the influence of heat generation or absorption on free convective flow and temperature transport within a wavy triangular enclosure filled by nanofluid taking Brownian effect nanoparticles. The water (H 2 O) employed as base fluid copper (Cu) nanoparticles for making effective Cu–H O nanofluids. perpendicular sinusoidally wall cooled at low while horizontal bottom sidewall heated non-uniformly (sinusoidal). inclined insulated. governing dimensionless non-linear PDEs are with help Galerkin weighted residual type finite element technique. simulated results displayed through average Nusselt number, isothermal contours, streamlines various model parameters such Hartmann Rayleigh parameter, volume fraction, undulation parameter. outcomes illustrate that rate augments significantly enhancement number well fraction whereas reduces increment Hartman number. transfer influenced size, shape, motion increases 20.43% considering 1% nanoparticle volume. thermal performance 8.66% blade shape instead spherical In addition, impacted small size 35.87% when from 100 10 nm. Moreover, transmission efficiently parameter rises. It also seen crucial factor in nanofluids generation/absorption influences distribution, rates, overall performance.

ABSTRACT A heat pipe with low thermal resistance and high conductance is one of the most effective transfer devices. It can move large amounts over a small cross-sectional area extremely little temperature variations between two limits. This study uses Design Expert software to evaluate performance various nanofluids as working fluid for pipe, including copper oxide, graphene iron titanium oxide. The base used in this analysis an aqueous solution n-Octanol. parameters considered are condenser flow rate, filling ratio, angle inclination, input. In order assess efficiency pipe's fluids, all operational factors assessed using Central Composite (CCD) matrix Response Surface Methodology during experiment design. experimental findings demonstrate that suggested model predict within 1% variation. As result, be forecast efficiency.
