Partial magnetic field and segmental heating effects on hybrid nanofluidic convection in a tilted porous wavy cavity

•Segmental heating dictates flow circulation, heat transfer, and entropy generation.•Enlarging by undulated walls enhances the heat exchange rate.•Bottom heating scenario maximizes fluid circulation and heat transfer (up to 132.91%).•LL or RR segmental heating is the best alternative to bottom heating.•Cavity and magnetic field angles at 90o enhance heat transfer.
