Abstract
Two-dimensional time-independent free convective flow and temperature flow into a right-angled triangle shape cavity charged by Cu-H2O nanofluid has been performed. The horizontal side of the enclosure is warmed uniformly T=Th whilst the standing wall is cooled at low-temperature T=Tc and hypotenuse of the triangular is insulated. The dimensionless non-linear governing PDEs have been solved numerically employing the robust PDE solver the Galerkin weighted residual finite element technique. An excellent agreement is founded between the previous, and present studies. The outcomes are displayed through streamline contours, isotherm contours, and local and average Nusselt number for buoyancy-driven parameter Rayleigh number, Hartmann number, and nanoparticles volume fraction. The outcomes show that the temperature flow value significantly changes for the increases of Rayleigh number, Hartmann number, and nanoparticles volume fraction. Average Nusselt number is increased for the composition of nanoparticles whereas diminishes with the increase of Hartmann number.
Highlights
Temperature transfer and fluid flow of nanofluids into the triangle shape enclosure have a wide applications in numerous industrial and engineering systems like heat exchangers, fire prevention, solar collectors, home ventilation systems, and refrigeration units etc
Influence of external magnetic field on natural convective flow into rectangle shape enclosure using warmed up and cooled neighbor walls was investigated by Ece and Buyuk (2006)
Free convective temperature flow value into nanofluids within an inclined was performed by Ghasemi and Aminossadati (2009)
Summary
Temperature transfer and fluid flow of nanofluids into the triangle shape enclosure have a wide applications in numerous industrial and engineering systems like heat exchangers, fire prevention, solar collectors, home ventilation systems, and refrigeration units etc. Cu -water, Al2O3 -water, and TiO2 -water are very common nanofluids. These nanofluids are used widely for the augmentation of temperature transfer. Free convective temperature flow value into nanofluids within an inclined was performed by Ghasemi and Aminossadati (2009). Impact of inclined angle using copper-water nanofluids within an enclosure was investigated Abu-Nada et al (2009). Numerical computations of FEM on convectional temperature flow into nanofluids within a rectangle shape enclosure was performed by Rahman et al
