dc.description.abstractIn the present work, performance assessment of a PCM filled three dimensional vertical cylinder is conducted under the combined effects of surface corrugation and presence of binary nanoparticles in the heat transfer fluid. The numerical simulation is performed by using finite element method with varying values of Reynolds number (100≤Re≤750), number (1≤N≤8) and height (H/10≤h≤H/2) of rectangular type corrugation form and volume fraction of particles (0≤ϕ≤0.02) in unsteady configuration. Thermal transport features are enhanced while charging time is reduced for higher values of Reynolds number, solid volume fraction of the binary mixture in the heat transfer fluid. Complete charging time is reduced by 57% with increase of Reynolds number from 100 to 750 while it is reduced by 23% when nanofluid at the highest solid volume fraction is used instead of water. However, the corrugation parameters have reverse effects on the charging process. A computational framework for reconstruction of heat transfer fluid and PCM temperatures for the unsteady parametric configuration in the computational domain is offered by utilizing proper orthogonal decomposition (POD) technique with 25 modes for heat transfer fluid and 75 modes for PCM. © 2021 Elsevier Ltd
