Hybrid lattice Boltzmann/Taguchi optimization approach for MHD nanofluid natural convection in a hemisphere cavity

In the present work, heat transfer optimization for natural convection with magneto hydrodynamic flow in the hemisphere enclosure embedded with a vertical isothermal cylinder is investigated using Taguchi method. The simulations were planned based on Taguchi's L25 orthogonal array with each trial performed under different magnetic field, heat source aspect ratio and particle volume fraction of nanofluid. The thermal lattice Boltzmann based on D3Q19 methods was purposed to simulate the flow and thermal fields. Signal-to-noise ratios analyses were carried out in order to determine the effects of process parameters and optimal factor settings. The present results provide a good approximation for choosing effective parameters of designing the thermal system.
