Solutions of Natural Convection of Nanofluids in a Parallelogrammic Enclosure by Finite Difference Method
Abstract: Detailed numerical
calculations for heat transfer enhancement utilizing nanofluids in a
parallelogrammic enclosure are presented in this paper. The sloping walls are
maintained isothermally at different temperatures. The top and bottom
horizontal straight walls are kept adiabatic. To simplify the effort in
matching the grid mesh with the sloping walls of the parallelogram, the
computational domain is mapped onto a rectangular shape using a non-linear axis
transformation. Transport equations are modeled by a stream-vorticity
formulation and are solved numerically by finite difference method. Based upon
the numerical predictions, the effect of the base angle of the parallelogrammic
enclosure on flow and temperature pattern and the heat transfer rate within the
enclosure are presented. Increasing the base angle was found to decrease the
heat transfer rate.
