Abstract

This paper discusses the application of Taguchi method in assessing maximum heat transfer rate for a natural convection with magneto hydrodynamic flow in a semicircle enclosure, embedded with a heat source. The simulations were planned based on Taguchi method with each trial performed under different magnetic field, heat source aspect ratio, and particle volume fraction of nanofluid. Thermal lattice Boltzmann methods was used to simulate flow and thermal fields. Signal-to-noise ratio analysis was carried out in order to determine the effects of process parameters and optimal factor settings. Finally, confirmation tests verified that Taguchi method achieved optimization of heat transfer rate with sufficient accuracy.
