Natural Convection

Natural Convection – Heat Transfer Similarly as for forced convection also natural convection heat transfer take place both by thermal diffusion (the random motion of fluid molecules) and by advection in which matter or heat is transported by the larger-scale motion of currents in the fluid At the surface energy flow occurs purely by conduction even in convection
