The phenomenon of natural convection of copper–water nanofluid inside a square cavity with time-periodic temperature is studied numerically. The studied configuration is subjected to a temperature gradient, with the bottom wall ( y  = 0) maintained to cold temperature and the top one ( y  =  L ) sub...
