Abstract

A computational analysis has been performed to study the effect of magnetic parameter on magneto-natural
convection and entropy generation inside a wavy cabinet filled by Al2O3-H2O nanosuspension. The vertical
boundaries of the cavity are designed as wavy and kept at cooled temperature (Tc), while the horizontal borders
are modeled as flat and supposed to be thermally insulated except the centrally heated portion on the bottom
wall. The higher constant temperature (Th) of the isothermal line source can supply thermal energy in uniform
manner. The transformed dimensionless governing equations were solved using finite volume technique along
with power-law scheme. The system was optimized for significant variety of controlling parameters namely,
number of undulations (N = 0–3), volume fraction of nanosuspension (ϕ = 0.0–0.04), magnetic parameter (Ha =
0 and 50), magnetic tilted angle (ζ = 0◦–90◦) and dimensionless heat difference (Ω = 0.001–0.1). The numerical
results are analyzed for streamlines, isotherms, entropy isolines, overall Nusselt number and average entropy
production strength. From this study, it is noticeable that growth of undulation number causes the reduction of
convective heat transfer rate as well as average entropy production intensity. Further, the findings elucidate that
the average entropy production intensity and overall heat transfer rate are decreased upon growing magnetic
parameter.
