The assessment of melting heat transfer and non-uniform heat source on magnetic
Cu–H2O nanofuid fow through a porous cylinder was studied. The transformed differential equations describing the motion of Cu–H2O fuid together with pertinent
boundary conditions were handled numerically with the assistance of Keller box
method. The ranges of volume fraction of copper particles were taken as 0–25%. The
impacts of various governing parameters on the physical measures such as Nusselt
number, surface drag force, temperature and velocity were analyzed by representing through graphs and tables. It was noted that the fow was infuenced accordingly
with the governing parameters. The outcomes showed that the rate of heat exchange
improved with elevated Reynolds number, space and temperature-dependent internal
heat source and melting parameters. The comparison of our data in relation to those of
previous works has been shown.
