dc.description.abstractIn this study, convective heat transfer and phase change process are analyzed for an L-shaped vented cavity equipped with an inner rotating cylinder and phase change material-packed bed (PCM-PB) system under magnetic field during hybrid nanofluid convection. The numerical work is performed for different values of Reynolds number (Re between 200-1000), rotational Rey-nolds number (Rew between-1000-1000), size of the cylinder (R between 0.05H-0.15H) and Hart-mann number (Ha between 0-40) while hybrid Ag/MgO nanoparticle loading amount in water is 2%. It is observed that the vortex size and their distributions in the cavity and within the PCM-PB system can be controlled by varying rotating cylinder size and rotational speed along with the magnetic field. With higher cylinder size, phase change becomes fast while complete phase tran-sition time (tP) is reduced by about 22% and average Nusselt number (Nu) rises by about 86% at Rew =-1000. Rotational direction of the cylinder is effective for phase transition dynamics while at Rew =-1000, tP rises up to 27% when compared to non-rotating cylinder case. Magnetic field strength is a good parameter for vortex suppression. At the highest strength, phase change becomes fast and average Nu rises up to 26.5% at Rew =-1000. ANFIS based modeling approach is used for impacts of rotating cylinder on the phase change dynamics in the L-shaped vented cavity. (c) 2022 THE AUTHORS.
